An itchy skin rash can be quite uncomfortable--and it might not always have a clear cause. But before you reach for an over-the-counter remedy, it’s important to see a dermatologist for a diagnosis. These skin rashes are often fungal skin infections and require special treatment. Here’s what you should know about the symptoms, treatment, and prevention of these infections.
There are several types of fungal infections that can affect the skin, most of which cause a scaly rash, redness, itching, blisters, swelling, and skin discoloration. Fungal skin infections often develop in areas with little air flow, since fungi thrive in warm and moist environments. So, you might notice these types of infections on the feet, underarms, and groin, for example.
Some of the most common types of fungal infections include:
While the above fungal skin infections are among the most common types, there are about 300 species of fungi that can infect humans. It’s essential to see a dermatologist for diagnosis and treatment if you develop an itchy skin rash.
Antifungal medications are the most common fungal skin infection treatment. These medications are available as creams, shampoos, sprays, and powers. Some people may require an oral antifungal. Your dermatologist will prescribe a medication based on the severity and location of your infection. It’s important to keep your dermatologist updated on the rash, as they may need to prescribe a stronger antifungal for persistent infections.
Fortunately, there are several steps you can take to prevent fungal skin rashes in the future. Be sure to change out of sweaty clothes after exercising and wear loose, breathable fabrics whenever possible. Avoid sharing towels, and always wear sandals when using a public locker room, pool, or shower. Your dermatologist can offer specific prevention tips based on your personal risk factors.
