My 23yr old son has severe pain in the soles of his feet, red spots, blisters between his toes, and intense itching on the soles and tops, and a tingling in the harder skin areas around his heels as well. The itching and red spots have spread to his hands...is this solely athlete s foot or could it be more since he s had a fever, fatigue, aches in his joints, swollen glands in the neck, and vomiting off and on over the past three days?
