Toenail fungus can cause an embarrassing discoloration of the toenails. Toenail fungus infections can make toenails change in color becoming whitish, yellow, or even brown. So, it is possible that the brown discoloration is caused by toenail fungus. 

If the brown discoloration is in fact caused by toenail fungus, then yes, the laser treatment may help. But if the discoloration is caused by bruising under the toenail or is the result of surface staining of the nail plate, then no, laser treatment would not help.  

A couple of questions may help determine how likely it is that the discoloration is caused by a fungal infection. 

1. How long ago did the discoloration begin.
2. Have you ever had athlete's foot?
3. Have ever had any trauma to the toenails where they became bruised under the toenail?
 
How Long Have You Had The Discoloration
Generally speaking, the longer the toenails have been infected, the more difficult it is to get rid of the fungus and return the toenails to a normal appearance. Some of this has to do with how much the matrix or root of the toenail has been stretched and or damaged by the thickening of the toenail. In some cases the thickening can become permanent. However the color will typically change significantly and improve after being successfully treated to remove the toenail fungus that is infecting the toenails. But, the toenail may remain thicker, if there has been damage to the matrix or root of the toenail. 

Athletes Foot
Athlete's foot is sometimes caused by the exact same fungus that infects the toenails. Toenail fungus is an infection of fungus in then toenails. Athletes foot is just a toenail fungus infection in the skin on the feet. If you have had athletes foot it s possible that you could have the fungus in your shoes that could lead to a toenail fungus infection.

Toenail Trauma
If you have repeatedly traumatized the nails by stubbing your type, or beating them up in running shoes, you may have bruising under the toenail. If there is bruising under the toenails, it may change the treatment options available to you. For example, if there is a large amount of dried blood underneath the toenail, the dried blood is dark in color and may absorb heat and burn the nail bed underneath the toenail if you were to have the laser toenail fungus removal procedure. In addition, a bruised toenail may look like a fungal toenail, but not actually be infected with toenail fungus. 

If you aren't sure whether or not the brown discoloration in the toenail is caused by a toenail fungus infection you can visit a podiatrist specializing in the treatment of toenail fungus. Another quicker option is to take a picture of the toenails and arrange a free remote email or phone consultation so you can get a better idea of the extent of the problem.

Dr. Christopher Segler is a podiatrist who specializes in the treatment of toenail fungus infections in San Francisco, Oakland, San Rafael and San Jose. He is board certified, American Board of Podiatric Medicine.  If you have a question about discoloration of the toenails that may be caused by toenail fungus you can call him directly at 415-308-0833.

This is a typical question from patients with mild cases of toenail fungus:

"Hi Doc...

I have a mild case of toenail fungus. Only the big toenails have the white spots and thicker nail that suggests a toenail fungal infection. However my dad’s toes are a different story. 

We recently had a house call podiatrist come to the home to check his feet. When I saw my dad’s toes, I was horrified at the sight of his toenails!  All of his toenails are yellow, thick and curving in odd directions. The big toenails are incredibly thick...nearly as thick as the toes themselves. They are crusty and flaking as well. Dad said that his toenails are so thick he hasn’t been able to cut them himself for years.

The podiatrist told us that super-thick fungal toenails are really not that rare in elderly people. He said that the appearance of dad’s fungal toenails is characteristic of a longstanding toenail fungus infection. 

My question is, “How long will it take for my mildly infected fungal toenails to get as thick as my father’s fungal toenails?”

The rate at which toenail fungus gets worse depends upon the type of fungus that has infected the toenail and your body’s ability to fight and slow the infection. 

Fortunately the most common forms of toenail fungus are not caused by overly aggressive organisms. Trychophyton rubrum and Trychophyton mentagrophytes are responsible for most of the toenail fungus infections. There are some less common fungal organisms that progress rapidly, but again, those are rare.

If you are young, healthy, have good blood circulation in your feet and have a strong immune system, you should expect the common forms of toenail fungus to get worse very slowly...almost unnoticeably slowly. You won’t notice any change from day-to-day. In fact, you may not see a change from month-to-month. 

If you takes pictures every few months and then compare over a long period of time, you may gradually notice that the areas of white and yellow discoloration are getting bigger. This may be your only indication that the toenail fungus is spreading and getting worse. If the fungus goes untreated for a long period, you may even notice that the toenail is getting thicker as well. 

But even if you are healthy and have a strong immune system that is fighting the toenail fungus infection, don’t expect your immune system to win. Toenail fungus is not something that you “get over” the way you might get over a cold or a case of the flu. When toenail fungus gets inside the toenail and starts to grow it is there to stay...unless you treat it. If you don’t treat the fungus it will simply continue to grow. 

Over time the fungus spreads throughout the toenail. As the toenail fungus grows, it begins to separate the keratin that forms the toenail. The cracks and splits in the keratin change the way light refracts through the toenail. Once that happens you notice white or yellow areas of the toenail where the keratin has been infiltrated and damaged by the thriving fungus. 

If the toenail fungus does enough damage, the nail plate may become misshapen enough to actually separate from the underlying nail bed. This usually creates large opaque white spot because the pink skin of the nail bed is no longer flush against the undersurface of the toenail. When this happens, it is usually at the end of the toenail in one of the corners.

As the fungal infection continues to get worse, the fungus bores its way through the toenail, moving closer to the root of the nail or “matrix.”  The toenails grows directly outward from the matrix. The matrix is the same size, same thickness and same curvature as a cross section of the toenail. 

If the fungus thickens the toenail and stretches out the matrix, the damage is permanent. At that point, even after you remove the fungus from the toenail, the matrix is permanently deformed and the toenail will always grow out thicker. 

If your immune system has been weakened by chronic disease, malnutrition, HIV infection or over-training, the fungus can grow and spread at a much faster rate. 

So, back to the real question. How long does it take for toenail fungus to become irreparably damaged and terribly thickened?

In many young healthy adults toenail fungus will worsen over the course of a year before the problem seems noticeable. In five years the common forms of toenail fungus can form substantial thickening and possibly permanent damage to the nail plate. But it may take ten years of more to develop the kind of grossly deformed thickened toenails like your father. The fact is, given what you describe, your father has likely had toenail fungus for decades.

With most technology-based equipment time affords remarkable increases in size and power. This is especially true of computers and other electronic devices. Today smart phones have more computing power than a laptop computer from just a few years ago.  All in much more compact design.

Laser technology has also had similar advancements and improvements. The A.R.C. Laser is one of the newest medical lasers on the market which can be used to remove toenail fungus. The A.R.C. Laser is significantly smaller, lighter and more compact than many of the previously introduced medical lasers. The laser fits in a briefcase and only weighs 4 pounds.

The small size and portability of this laser makes it possible for us to bring the laser to the homes of patients all over the San Francisco Bay area in order to perform laser toenail fungus removal treatments at home.

The Pinpointe laser for example is so much larger and heavier that it would be virtually impossible for our podiatrist to bring the Pinpointe laser into your home or office to perform your laser toenail fungus treatment. 

Toenail fungus can be an embarrassing condition. Although it is extremely common, many people do not feel comfortable exposing their yellow cracking toenails in public. For this reason house calls to treat toenail fungus can help to alleviate this anxiety and discomfort. 

Dr. Christopher Segler is Board Certified, American Board of Podiatric Medicine.  He makes podiatry house calls to perform laser treatment to treat toenail fungus in San Francisco, Mill Valley, San Rafael, Oakland, Berkeley, San Jose and Palo Alto. If you have toenail fungus and wonder if laser treatment at home can help remove the toenail fungus so you can develop clear toenails again, you can call and speak directly to our podiatrist to ask questions. Call 415-308-0833 to reach Dr. Segler directly. 

This video explains how clear toenails turn into discolored fungal toenails.

A normal toenail is thin, clear and translucent allowing you to actually see right through the toenail to the pink nail bed underneath. However as soon as the fungal spores get in underneath the toenail the toenail fungus starts to grow within the keratin of the toenail itself. The growing fungus actually causes the layers of keratin to separate.

The separation of layers within the toenail causes the toenail to become thicker but it also changes the way that light refracts through the toenail. This causes a cloudy discoloration that is usually white or yellowish. Those thick, crumbling white and yellow areas of the toenail are the classic signs of a toenail fungus infection.

If you think you might have a toenail fungus infection, you can call 415-308-0833 to speak to an expert to find out if you might be able to get rid of the toenail fungus and have clear toenails again. 

Funky ugly toenails seem to plague runners. Toenail fungus is one cause of thick yellow toenails and it is very common. In fact 14% of Americans have toenail fungus. Based on this, if you are out for a run with six other runners, one of you probably has toenail fungus. 

Although running shoes can put you at risk of toenail fungus there are some simple steps you can take to prevent a toenail fungus infection from your running shoes.

Guns Don’t Kill People...

But flying bullets sure do! Spores are the seeds that give rise to a foot fungus infection. The spores are everywhere. And if they get into your shoes they can grow and multiply. The more fungal spores in your shoes, the more risk of toenail fungus infection. 

Active fungus thrives in any environment that is dark, warm and moist...like the inside of your running shoe. Running shoes are the perfect incubators for toenail fungus! If you get spores in there the active fungus starts to grow and sheds even more spores inside your running shoe. 

The Real Problem...

The worst thing you can do is rush into the house after you finish your run, take off your running shoes and throw them into a dark, poorly ventilated closet. Or if you have been running on the treadmill at the gym you take your shoes and stuff them into your gym bag. 

Your damp running shoes will then sit in the dark and any fungus will thrive in that moisture from your sweaty feet. If you run every day, the running shoes never really completely dry out. These are ripe conditions for toenail fungus. 

The next day you put on your running shoes and head out the door. Not only is there active fungus within your running shoes but you have fungal spores which are basically the seeds for toenail fungus all lining the interior of your running shoes.

So as you are running your toes hit the inside of the running shoes the fungal spores get wedged in between the toenail and the skin underneath. If you have any trauma to your toenails such as banging the end of the running shoe when you're running up or down hill (or stopping quickly) the fungal spores can actually get into the nail bed and start to develop a toenail fungal infection.

Once that happens the toenail fungus actually grows within the keratin of the nail plate separating all of the layers of the keratin and making the toenail thicker.

All of that separation of layers in keratin of the toenail plate causes light to refract unevenly through the toenail. This is what causes the discoloration and crumbling of the toenail that creates the ugly appearance.

While it is possible to treat the toenail infection and kill the fungus, it is critical that you reduce your exposure to the fungus spores if you want to keep your toenails clear.  Remember, you have to stay out of the line of fire if you don’t want to get hit by the bullets. 

You must prevent the accumulation of active toenail fungus and fungal spores in your running shoes. If you don't, it will just be a matter of time before you get a fungal foot infection.

The best defense for a runner against toenail fungus is to make sure that you dry your running shoes out completely. Leave them somewhere where they will dry near a heating vent or in the sunlight.

If you are a high mileage runner and run on back-to-back days it might be a good idea to buy 2 pairs of running shoes. Alternate the running shoes so that they have a chance to dry out completely. This won't be any more expensive because the running shoes will last twice as long.

It is also important to make sure that your running shoes fit correctly. If your toes are bumping the end of the shoes (as evidenced by discoloration such as bruising or dark spots under the toenail) you might actually be traumatizing the toenails when you run. This trauma to the toenail puts you at enormous risk of developing toenail fungus.

If you had athlete’s foot or toenail fungus in the past you have to kill of all the fungus in your running shoes. The easiest way to do this is to use an ultraviolet shoes sanitizer. Ultraviolet light will actually kill all of the fungus without any odor or toxic chemicals. The other alternative is to spray the inside issues with chemical disinfectant. If you use a disinfectant spray to kill the fungus in your running shoes make sure that it dries out completely before you wear them again.

As long as you keep the fungus out of your running shoes and allow your shoes running shoes to dry completely after your workouts you should be able to prevent your toenails from turning yellow as the result of a toenail fungus infection.

The laser treatment will kill the fungus in your toenails. But to keep your toenail clear after the laser toenail fungus treatment you have to make sure you don’t get re-infected with toenail fungus. Up to 50% of patients who effectively treat the toenail fungus infection will get the nasty infection again within a few years. 

The key is to keep the fungal spores under control.

Spores are basically the seeds from which toenail fungus grows. They are very durable. In fact, fungal spores can lay dormant for many years and still remain viable. Just place the spores in a warm, moist, dark environment and they will start to grow sprouting a new toe fungus infection. 

The laser will effectively remove the fungus from your toenails, but that is only the first step.

The whole time you have had a fungal infection, you have been shedding fungal spores into your shoes and socks. Getting free of the spores is the best way to prevent the fungus from infecting your toenails again. 

1. Wash all of your socks in hot water. This will get rid of the fungus and spores in your socks. Some people throw out all of their socks and replace them. But this isn’t really necessary. 

2. Kill the fungus in your shoes. Use an antiseptic spray or an ultraviolet sanitizer to kill the spores and live fungus in your shoes. Bowling alleys have been doing this forever. They simply spray some toxic chemicals in the bowling shoes to kill all of the germs between rentals. Sprays like Lysol will work, but frankly they make your shoes smell like Lysol. So if you are going to try this, make sure you test it out on a pair of shoes you aren’t crazy about before you spray all of your shoes. The Steri-Shoe is a much nicer alternative. It uses ultraviolet light to destroy the live fungus and spores in your shoes. No smell, no toxic chemicals and no waiting to dry the shoes out. You can order one online at a discount here.

3. Watch out for and aggressively treat any athlete’s foot. The fungus that causes athlete’s foot is the same one that causes toenail fungus infections. Those little spots of peeling skin are the classic sign of athlete’s foot. Many people think that if the skin doesn’t itch, it isn’t athlete’s foot. This is false. 

Every time I see a patient who wants the toenail fungus laser removal treatment I ask them if they ever get athlete’s foot. Less than 10% say yes. But about half of all the laser toenail patients actually have signs of an active case of athlete’s foot that they haven’t even noticed. 

So it is possible that you could pick up a case of athlete’s foot and not realize it. You should check your feet every day. Look for peeling skin around the edge of the sole and between the toes. 

If you get athletes foot, you are actually growing fungus between the layers of skin. As the skin peels, fungal spores are shed into your socks and shoes. Then all it takes is to bump your toenails on the inside of the shoe and those spores can get in again start another toenail fungus infection.

If you notice some athlete’s foot don’t panic. You can simply apply an over-the-counter cream for a couple of weeks to cure the skin infection. Of course you will want to use the Steri-shoe ultraviolet sanitizer in your shoes again and wash your socks in hot water, just like you did after the laser procedure.

Taking these simple precautions you will help ensure that your toes stay clear, healthy and fungus free!  If you have a question about a toenail fungus infection, call the toenail fungus expert directly at 415-308-0833.

Dr. Christopher Segler is a San Francisco based podiatrist and is board certified, American Board of Podiatric Medicine.  His practice provides house calls to people who are just too busy to sit in traffic or a doctor's office. He sees patients in their own homes to treat their toenail fungal infections with one of the newest lasers available. We do house calls in San Francisco, Oakland, Berkeley, San Rafael, Mill Valley, San Mateo and San Jose. If you have a question about toenail fungus and wonder whether or not the laser fungus removal treatment will help you have clear toenails again, you can call and ask a toenail expert by calling 415-308-0833.  And yes, you will actually get to speak with the doctor. 

Many medical terms seem unnecessarily long and complicated.  him and toenail fungus is no different. “White superficial onychomycosis”  is a purely descriptive term.  “White” of course refers to the color. “Superficial” implies that the fungal infection is only really affecting the surface of the toenail. “Onychomycosis” means fungal infection of the nail. 

When you put all of this together of course what it tells you or the doctor is that there is a fungal infection involving the toenail that is causing the toenail to become white and discolored and is only on the surface of the nail plate.

In general these superficial toenail infections do not penetrate the toenail itself.  The toenail will look like it has some white spots or speckled appearance. It sort of looks like there are powder sugar in splotches on the toenail. This particular form of a toenail infection can be related to applications of nail varnish or toenail polish base coats. 

Although this is not the most common form of toenail fungal infections, it can be easier to treat. The reason that it might be easier to cure is that the infective organisms are closer to the surface and not underneath the nail plate where they can be harder to reach.

Because the fungus is actually growing on the surface of the nail plate it is also easier for your podiatrist to take a sample of the fungus and evaluate it.  It may also respond to topical treatment more readily than a fungus that bores all the way through the nail plate down to the nail bed. The laser treatment is also effective for this type of toenail fungus infection.

One question we often get is whether or not toenail polish has to be removed in order to treat the toenail fungus. The answer is yes.  All nail polish must be removed prior to the laser treatment

A laser is really nothing more than highly concentrated light energy. Light energy is absorbed by colored toenail polish, particularly dark colored toenail polish.

In order to treat the toenail fungus, you must remove the toenail polish before laser fungus treatment.  If you didn't, the laser would vaporize the nail polish. This would generate an enormous amount of heat which would potentially damage the nail plate or even the nail bed underneath the toenail.

Dr. Christopher Segler is Board-Certified,  American Board of Podiatric Medicine.  He performs all laser treatments himself and does not utilize non-physician staff to perform laser fungal treatments. If you have a question about laser treatment of toenail fungus, you can call the doctor directly at 415-308-0833.

If you have only one toe nail that has become infected with a fungal infection you may choose to only perform the laser treatment on that single funky toenail. The laser treatment can successfully kill and remove the fungus from a single thick, yellowing, discolored toenail, and you do not have to treat all of the clear toenails. The problem with this approach is that there is a high recurrence of fungal infections after the fungus has been killed. When you get reinfected, the previously infected, clearing, healthy appearing toenail may start to become yellow and thicker if it starts to get infected again.

There are three primary reasons you might get another toenail infection after successful laser treatment.
1. You have an early fungal toenail infection in one of the other toes on the same foot. If the fungus has just started to invade one of the other toenails on your foot, you might have fungus growing there, even though it hasn’t yet caused the yellow, thick and ugly appearance expected with a fungal toe nail. 

If you only treat the thick yellow nail that is obviously infected, but not the other nails on the same foot, you run the risk of leaving live fungus behind that can restart a fungal toenail infection and spread to the other toes. 

2. You have fungal spores in your shoes that can start a re-infection of toe fungus after the toenail laser has removed the fungus in the toenail. The spores are essentially microscopic seeds that sprout fungus. When you have toenail fungus, the crusty white debris that accumulates under the end of the toenail is loaded with fungal spores. As you walk around, the fungal spores are shed and land in your shoes. The warmth from you feet, moisture from sweaty feet and darkness inside the shoe creates the ideal environment to sprout a now fungus infection from the old spores sitting in your shoes. You can help prevent a re-infection of toe fungus by spraying you shoes with Lysol disinfectant (if you don’t mind the smell) or you can simply kill the fungus in your shoes with a Steri-Shoe ultraviolet sterilizer. that will use ultraviolet light (which kills fungus) to kill all of the spores and fungus in your shoes. 

3. You are simply susceptible to toenail fungus and fungal infections like athletes foot.
Just like some people are more prone to allergies or catching a cold, some feet are more prone to picking up fungal infections in the skin of the feet and toenails. Athlete’s foot is a fungal infection of the skin. Onychomycosis is a fungal infection of the nail. The same fungal organism that causes athlete’s foot is the same fungal organism that causes toenail fungus. If you have had many cases of athlete’s foot, you will want to stay alert for athlete’s foot. When you start noticing an athlete’s foot infection after your toenail infection has cleared with the laser treatment, you will want to aggressively treat the athlete’s foot before the fungus in the skin spreads to the toenails. You should also kill the fungus in your shoes with a Steri-Shoe ultraviolet sterilizer.
