Your risk of tinea pedis is greater if you do not wash your feet or do not change your socks every day. signs and symptoms:- Cracks or blisters Redness, swelling, itching, or burning Scaly or peeling skin Bad smelling feet Thick, dark skin on the bottoms or sides of your feet Thick, abnormal toenails Tinea pedis is usually treated with an antifungal medicine. This medicine may be given as a cream, gel, or pill. You may need a doctor's order for this medicine. Take it until it is gone, even if your feet look like they are healed. The fungus may spread and cause other skin infections. It is possible to get tinea pedis more than once. Keep your feet clean and dry: Wash your feet each day and dry them well, especially between your toes. After your feet are dry, put powder on your feet and between your toes. Wear clean cotton or wool socks each day. Put your socks on first so you do not spread the infection to other areas of your body. Wear sandals, canvas tennis shoes, or other shoes that allow air to flow to your feet. This helps keep your feet dry. Avoid plastic or rubber shoes. Soak your feet: If you have blisters, soak your feet in an astringent (drying) solution. Do this for 20 to 30 minutes, 2 times each day to help dry out the blisters. An astringent solution may be bought at drug or grocery stores. Wear shoes in public areas: Do not walk barefoot in public places. Wear shower shoes or sandals in warm, damp areas. kindly stop using tooth paste and contact dermatologist.
