Toenail fungus
Thick, yellow, or crumbly toenails are often caused by a fungus. It is common, and there are several ways to manage it.
What is it?
Toenail fungus (onychomycosis) is an infection under and inside the nail. The fungus grows best in warm, damp places, like the inside of shoes. It often starts at the tip or edge of the nail and slowly spreads.
It is more common as we get older, and in people with diabetes, poor circulation, or athlete's foot. It can be hard to clear because the nail grows slowly and the fungus lives under the hard nail, where medicine has trouble reaching.
Signs to watch for
- Nails that are thick and hard to trim
- Yellow, white, or brown color
- Nails that crumble or break easily
- A nail that lifts away from the skin
- Pain or pressure in shoes from a thick nail
Care at home
- Keep feet clean and dry, especially between the toes
- Change socks if they get damp
- Wear shower shoes in public showers and pool areas
- Do not share nail clippers or files
- Treat athlete's foot early so it does not spread to the nails
Treatment options
Other problems can make nails look like this, so Dr. Nafal may take a small nail sample to test it. This helps confirm the cause before you start treatment. He will then explain your options in plain words.
- Prescription medicine you put on the nail (topical medicine)
- Prescription pills (oral medicine), when they are a good fit for you; this may include blood tests to check your health while you take them
- Regular trimming and thinning of thick nails in the office (debridement) to ease pressure and pain
Be patient. Toenails grow slowly. It can take many months for a clear nail to grow out, and the fungus can come back.
If you have diabetes or poor circulation, thick nails can press on the skin and cause sores. Please do not dig at or cut thick nails yourself. A foot doctor can trim them safely. If you see redness that spreads, pus, an open sore, or have a fever, be seen right away.
Common questions
Will over-the-counter products work?
They may help mild cases, but they often have trouble reaching fungus deep in the nail. A visit can help you find a plan that fits your nails and your health.
Can toenail fungus come back?
Yes, it can. Keeping feet dry, wearing shower shoes, and treating athlete's foot early can lower the chance.
