Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness, and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons, and other tissues. Gout is most common in men.
Gout is caused by too much uric acid in the blood. Most of the time, having too much uric acid isn't harmful. Many people with high levels in their blood never get gout. But when uric acid levels in your blood are too high, the uric acid may form hard crystals in your joints.
Your chances of getting gout are higher if you are overweight, drink too much alcohol, or eat too much meat and fish that are high in chemicals called purines. Some medicines, such as water pills (diuretics), can also bring on gout.
The most common sign of gout is a nighttime attack of swelling, tenderness, redness, and sharp pain in your big toe . You can also get gout attacks in your foot, ankle, or knees, or other joints. The attacks can last a few days or many weeks before the pain goes away. Another attack may not happen for months or years.
See your doctor even if your pain from gout is gone. The buildup of uric acid that led to your gout attack can still harm your joints.
Your doctor will ask questions about your symptoms and do a physical exam. Your doctor may also take a sample of fluid from your joint to look for uric acid crystals. This is the best way to test for gout. Your doctor may also do a blood test to measure the amount of uric acid in your blood.
To stop a gout attack, your doctor can give you a shot of corticosteroids or prescribe a large daily dose of one or more medicines. The doses will get smaller as your symptoms go away. Relief from a gout attack often begins within 24 hours if you start treatment right away.
