Uric acid down foot pain may be caused by uric acid metabolism disorders, deposited urate crystals have not disappeared and other reasons. 1. Uric acid metabolism disorder: foot pain can be considered to be caused by uric acid metabolism disorder. Due to the long-term increase in the concentration of uric acid, the formation of urate crystals will be deposited in the joints and other parts of the joints, which in turn stimulate the synovial membrane of the joints to produce inflammatory factors, thus causing redness, swelling, pain and these symptoms. 2. Deposited urate crystals have not disappeared: Although the uric acid in the blood is at a normal level, the deposited urate crystals have not disappeared, so the patient’s foot pain symptoms will occur. Treatment of gouty arthritis is not just about whether the uric acid is normal or not, it is a long-term treatment process, blood uric acid is kept at a relatively low level for a long time, the deposited urate crystals are slowly released and dissolved, and the symptoms of gout will gradually improve. It is recommended that gout patients seek medical attention in time to avoid delays.
