Gout is a form of arthritis caused by the accumulation of uric acid in the joints. It is an extremely painful disease.  Gout is characterized by sudden, excruciating pain, swelling, redness, warmness and stiffness in the joint. Low-grade fever may also be a symptom. Gout sufferers will often experience intense pain whenever the affected area is moved. In addition, the inflammation of the swollen tissues around the joint also causes the skin to be swollen, tender, and sore even if it is slightly touched. The act of draping a blanket over the area, for example, would be very painful.

Gout usually affects the big toe, but can also attack other joints. These joints include the ankle, heel, instep, knee, wrist, elbow, fingers, and spine. A diagnosis is generally made on a clinical basis, although tests are often required to confirm the diagnosis of the disease. Blood tests commonly performed are full blood count, electrolytes, renal function, and erythrocyte sedimentation rate. They are used mainly to exclude other forms of arthritis.
