Hello, Thanks for writing to us. Athlete s foot, a common fungal infection, causes peeling, itching and stinging skin on the big toe. The fungus can also spread to the toenails, resulting in crumbling. Your chances of getting a fungal infection increase when the skin is wet for long periods of time. An over-the-counter medication such as butenafine or clotrimazole treats athlete s foot infections. Use the medication and directed and keep the feet dry. If nonprescription methods aren t getting rid of big toe peeling, contact your doctor. Avoid bare feet while in public places, such as locker rooms and pools. Select socks made from natural materials, like cotton. I do hope that you have found something helpful and I will be glad to answer any further query.
