Gout Health Center
Gout, one of the most common forms of inflammatory arthritis, often causes extreme pain, joint swelling, warmth, and redness. It is caused by a buildup of uric acid crystals in the soft tissue of a joint. Most cases of gout occur in the big toe, but it can affect other joints in the foot, or joints in the knee, elbow, wrist, and fingertips. Gout episodes last between a few days and a few weeks, and pain from gout often flares up at night.
