is caused by too much uric acid in the blood (hyperuricemia). Hyperuricemia
usually does no harm. But sometimes when uric acid levels in the blood are too
high, uric acid forms crystals that build up in the joints. The crystals can
cause a gout attack. A gout attack typically causes pain, swelling, redness,
and warmth (inflammation) in a single joint, most often the big toe.
