Feet turn red from gout, bunions and athlete's foot, according to Mayo Clinic, WebMD and Lifescript. Gout is a painful form of arthritis, athlete's foot is a fungal infection, and bunions are a joint deformity.
The symptoms of gout include redness and tenderness in specific joints, often in the feet and especially in the big toe, accompanied by severe and potentially debilitating pain, according to Mayo Clinic. The pain of gout often awakens sufferers in the middle of the night and is so acute that even resting a sheet on an affected joint causes unbearable pain. Gout is a treatable condition.
Bunions form when the big toe pushes against the next toe, forcing the metatarsophalangeal joint, which is located at the base of the big toe, to grow bigger, stick out from the side of the foot and become painful and red, explains WebMD. Bunions are caused by wearing tight, narrow shoes; structural defects in the foot; and arthritis. The symptoms of bunions and gout are often confused, but the two conditions differ in that gout comes on quickly while bunions develop slowly.
Athlete's foot often causes an itchy red rash and severe skin scaling. The fungus that causes athlete's foot may cause the skin to crack, leading to bacterial infections, notes Lifescript.
