Gout is one of the most painful rheumatic diseases. It results from deposits of needle-like crystals of uric acid in the connective tissue, joint spaces, or both. These deposits lead to inflammatory arthritis, which causes swelling, redness, heat, pain, and stiffness in the joints.
Arthritis is a term that is often used to refer to the more than 100 different rheumatic diseases that affect the joints, muscles, and bones, and may also affect other connective tissues. Gout accounts for about 5 percent of all cases of arthritis.
