Gout occurs when there is increased levels of uric acid in the blood and this deposits in a joint, most commonly the big toe joint in the foot.  The accumulation causes crystals to form and the inflammation can be extremely painful.  It appears as a red, hot swollen, painful joint and even sheets touching the foot are unbearable. Patients with gout have an elevated uric acid level. Your doctor may order a uric level blood test to measure the amount of uric acid.  If it comes back elevated, then you should see your primary care doctor in order to take medications to decrease the uric acid levels and thus prevent another gout attack.
