Gout is a condition where crystals build up in the body and cause joints to become very painful. Once treated, gout is not a problem for most people. What happens? Gout is caused by uric acid crystals in the joints. We all have some uric acid in our blood but most of us pass out enough uric acid in our urine to keep down the amount in our blood. However, some people don’t pass enough, or they produce more in the first place so the level of uric acid in blood and tissue fluids is higher.

When there is too much uric acid in the tissues, it can form crystals. These crystals can form in and around joints. If crystals enter the joint space they cause inflammation, swelling – and severe pain.
