Gout is a form of arthritis characterized by sudden and severe episodes of pain, redness, and swelling in the affected joints, often beginning in the big toe. The condition results from the accumulation of uric acid crystals in the joints, which forms when the body produces too much uric acid or fails to excrete it efficiently. These crystals trigger intense inflammation and pain, leading to the classic symptoms of gout.

In patients, gout most commonly affects the feet because the lower extremities are cooler than the rest of the body, which can promote the formation of uric acid crystals. The big toe is particularly vulnerable, but gout can also impact other joints in the feet and ankles. During an attack, even the lightest touch can be extremely painful, and the affected area may become warm, red, and swollen. Chronic gout can lead to joint damage and deformities if not properly managed, often necessitating lifestyle and dietary changes alongside medications to control uric acid levels and manage symptoms effectively.
