Gout frequently involves joints in the lower extremities. The classic location for gout to occur is the big toe. Podagra is the medical term for inflammation at the base of the big toe. Gout can also affect the foot, knee, ankle, elbow, wrist, hands, or nearly any joint in the body. When gout is more severe or longstanding, multiple joints may be affected at the same time. This causes pain and joint stiffness in multiple joints. Another sign of gout is the presence of tophi.
