Chronic health conditions like renal failure or certain genetic disorders that predispose individuals to crystal deposits.
Key Symptoms: Sudden episodes of intense joint pain, especially in the ankle and foot. Swelling and tenderness around the affected joint. Redness and warmth in the joint area. Limited range of motion due to pain and swelling. Recurring flare-ups that may become more frequent over time. Possible formation of tophi or under-the-skin crystal deposits in chronic cases.
