I have a rash on the top of my foot, it itches alot. just wondering what.it could bek?

Fungal infection: This may be a fungal infection (athlete's foot). This is common in men. You can try an otc anti-fungal cream or powder to start off to see if it works. Also, wash your socks often and use anti-fungal spray inside all of your shoes and slippers.

More info needed: Is the rash on both feet? Is this a recent rash? Have you recently changed shoes? Thanks.

Tinea pedis or derma: The rash could be tinea pedis (athletes foot) fungus of the skin or could be a localized dermatitis caused by contact with an allergen. Otc antifungal cream applied 2 x daily if it is a fungus should show signs of improvement in 4-7 days with itching stopping in 48 hours. If that fails try Hydrocortisone cream 2 x daily. If that does not resolve the itching and rash see your foot doctor.

Rash: Conditions such as eczema, and irritant or contact dermatitis may involve the top of the foot and can itch. Fungal infections involve the toe web spaces and sides of the feet typically. See your dermatologist for a diagnosis and treatment.
