Athlete's foot - what does it look like and how to treat it?

Foot fungus is a common problem that can affect people of all ages, both healthy and chronically ill. The infection can take many forms and proceed with symptoms such as itching, peeling, redness, cracks and even ulcers in the feet. Treatment of foot fungus is based primarily on topical treatment with the use of creams, gels, aerosols and powders containing antifungal substances.
