Gout

Gout is a form of arthritis caused by a buildup of uric acid crystals in a joint. It causes sudden attacks of pain, swelling, redness, and stiffness, usually in one joint. It happens most often in the big toe.

Gout usually comes on without a cause. But it can be brought on by drinking alcohol (especially beer), eating or drinking things made with high-fructose corn syrup, or eating seafood or red meat. Taking certain medicines, such as diuretics, can also trigger an attack of gout.
