Many different skin problems affect your feet, some more common than others. The usual cause of rash or skin lesions on the feet is an infection, whether it's fungal, bacterial, or viral. Simple irritation or allergic reactions are also a fairly common cause of the rash. Sometimes these skin conditions have similar characteristics, which makes them tricky to identify or to treat with over-the-counter products. It's best to seek medical attention for the diagnosis and treatment of these conditions.
