Health experts have confirmed that fungi is present in and on the body and therefore fungal infections can affect any part of the body. Toenail fungal infections are unfortunately one of the more common infections people can contract. How can you detect whether or not you have a toenail fungal infection? Here are the top five clues to look for to determine if you have one:

1. Toenail color changes 
One of the common changes will be development of yellow streaks under the nails. Health experts consider this the initial sign that an infection is developing. If the nail in question turns green, there is definitely an infection and it is likely bacterial. White and yellow nails indicate fungal and yeast infections. Yellow nails indicate fungus. In some cases, however, the color change is more subtle. The shininess of the nail simply fades. Other times the nails turn a darker color than normal. If you regularly paint your toenails, it's a good idea to take off the polish completely once in a while to check on your nail bed’s color. 

2. Toenail texture changes
If your toenails become exceptionally brittle or have begun to thicken you could be suffering from an infection. In some cases the toenails will break, or the shape will become distorted by the growing fungus.
 
3. Toenail separation
In some cases of toenail fungal infection, the nail can completely separate from the nail bed. If you have not recently stubbed your toe or endured any similar injuries, this could be an indication of trouble. The unfortunate thing is sometimes when you have a fungus-related infection you won't even feel the separation. Therefore, it's even more critical to regularly examine your feet.

4. Pain
As the infection advances, pain may be felt on the affected part. Furthermore, the surrounding tissues may get inflamed. Pain is attributed to the thickening nails. If you gently press the nail and find the area is tender or sore, you could have an infection. It is also important to clarify that the pain is not a result of tight footwear or other toe conditions, however.

5. Odor
A bad smell is another reliable indication that you have a toenail fungal infection. As the fungus causes the toe tissues to die, an odor will be given off. This option is relatively tricky because bad smell can be caused by other factors apart from fungal infection. For example, wearing shoes for a long time can lead to the development of unpleasant odors. This is common in people whose feet sweat. Because of this many people will go undiagnosed, simply assuming they have stinky feet. If this is the case and you're not quite ready to seek medical confirmation, wear open footwear such as sandals for a couple of days. If you still have an odor, it's a pretty clear indication there is trouble afoot. 
​
Other indications include a discharge of pus, running a fever and red streaks around the area. If you suspect you have a toenail fungal infection, visiting a doctor isn't a bad idea. Your case may or may not warrant prescription medication, but it's better to know what you're dealing with than play the wait and see if it gets better game.

QUESTION:

Hi Doc!

My boyfriend has toenail fungus on both feet and he had a discount laser treatment from another clinic about 6 months ago. We were hoping that this would help, but his toenails still look like they are the same as before the laser treatment. The fungal toenails are still yellow, thick and crumbly. He hasn't had any improvement at all.  If laser treatment did't help, are there other options that he can try?

Thanks!
CJ.

ANSWER:

Hello CJ, 

I am sorry to hear your boyfriend has not made a full recovery. If he had a laser treatment and the toenails didn't get better, he still has several options:

Laser Re-Treatment
1. Re-treatment with the laser. This is the fastest way to kill the fungus. But if we do this, we should schedule more than an hour. I would recommend doing a double laser treatment in one setting. Basically, I would just make sure that the treatment is so thorough that there is no way the fungus could live through it. 

Prescription Anti-fungal Pills
2. Prescription terbinifine pills. If I give your boyfriend a prescription for the course of pills, he will need to have a blood test to make sure his liver is in good shape before beginning the course of medication. He would then need to have a blood test again in 6 weeks to make sure he isn't having liver damage. The prescription medication can cost more than laser treatment. And the pills can alter your taste (making some foods have a metallic taste) but it is usually transient and goes away once he stops taking the medication. Also, he CANNOT drink alcohol while taking the anti fungal pills. 

Prescription Strength Topicals
3. Prescription topical anti-fungal medications can also work, but they can tedious and very expensive. The advantage over the pills is that there is no risk of liver damage. I have seen one patient that had a bad reaction where he had to stop using it because the skin around the toenail became very red and inflamed. But this is not typical, and the redness and pain did resolve after he stopped using the topical anti-fungal on his toenail. The topical solution is applied to the toenails daily. They to be applied every day for almost a year. I have had patients tell me that they often need a few tubes of these medications since they have to apply it for almost a year. The cost can vary depending upon which pharmacy you use, but most patients have said they paid over $500 per tube in some cases. You would want to check with your pharmacy to inquire about cost before getting started, just to make sure it wouldn't be too expensive. 

No matter which treatment your boyfriend prefers, we have to make sure that he has NO Athlete's foot at all trying another treatment. If there is any peeling skin on the feet that looks like an athlete's foot infection, then I would suggest either a month of a topical anti fungal on the skin, or a 2 week course of the oral anti fungal prescription pills (instead of 3 months) just to clear the skin fungal infection. Once the fungus has been removed from the skin, we could do the laser treatment to clear the toenail infection.

Making sure there is no athlete's foot is critical to success.
