What is a quick way to treat tinea pedis, or eczema..not sure what i have on my feet?

OTC creams: Tinea pedis or athlete's foot often involves the area between the toes. Anti fungal creams are effective for tines pedis whereas Hydrocortisone cream would typically be effective for eczema. Most cases of eczema need moisturizing while tines pedis areas need to be kept dry.

Try OTC anti-fungus : Otc anti-fungus meds if that does not work try otc cortisone cream for non tines.

Which one?: The treatment for athletes foot and eczema are very different. Both can be treated well with topical creams, but the medications are very different. You should see your doctor to confirm your diagnosis.
