Foot skin infections include plantars’ warts (often caused by a virus); the common disease athlete's foot (tinea pedis), which is caused by a foot fungus that thrives in warm, humid conditions; and a bacterial infection called pitted keratolysis, which is also associated with warm, damp feet. Hand-foot-and-mouth disease is a viral infection causing blisters of not only the feet but also the palms and mouth. Information on toenail fungus can be found on our toenails information page.
Skin diseases that affect the foot include dyshidrotic eczema, which is associated with tiny, itchy blisters of the palms, fingers, instep of the foot, or the toes. These blisters then turn into peeling, cracking, or crusting areas. Gout is a form of arthritis, which is the inflammation of a joint. Gout most commonly affects the big toe joint, and it typically starts as an acute attack with severe pain and swelling in the joint.
