Symptoms of onychomycosis

There are many symptoms associated with onychomycosis, the most common of which are pain, inflammation, and reduced nail flexibility. Some people may also experience scaling or redness on their nails. If left untreated, onychomycosis can lead to corns and even nail loss.

How to diagnose onychomycosis

Onychomycosis is a fungal infection of the nails. The fungus can grow on any part of the nail, but is most commonly found on the center (palmoma) or end (onion) of the nail.

Nails that are affected by onychomycosis may look white or yellow and may have cracks or ridges. The fungus can also cause excessive growth of the nail plate, which can make it difficult to remove nails during surgery.

There are several ways to diagnose onychomycosis. A doctor may take a sample of your nail to test for fungus. Or, he or she may perform a skin test in which tiny pieces of fungal material are put on your skin and later seen to grow.

If you suspect that you have onychomycosis, you should see your doctor as soon as possible. Treatment typically involves topical antifungal medications applied to the infected area twice a day for four weeks or more. In some cases, surgery is required to remove the fungus completely from the nail.

Treatment of onychomycosis

Onychomycosis is a fungal infection of the nails. The fungus that causes onychomycosis grows in moist areas of the skin, such as under the nail and around the cuticles. The infection can occur on any finger or toe, but is most common on the fingers. Onychomycosis can be treated with antifungal medication. Treatment usually lasts about six months.

Prevention of onychomycosis

Onychomycosis is a fungal infection of the nail that can be prevented with regular cleaning and treatment. It’s most common in people over 50, but can affect anyone. To know if you have onychomycosis, ask your doctor to take a look at your nails.
There are a few key things you can do to prevent onychomycosis:
-Wash your hands often, especially before and after you handle food.
-Keep your nails short and clean.
-Avoid using harsh chemicals or abrasives on your nails.
-Get treatment for onychomycosis if it develops.
