In this case, it is necessary to consider that the inflammation of the joint is still present due to incomplete treatment of gouty arthritis or rapid decrease of uric acid. When uric acid decreases, the uric acid crystals continue to dissolve into uric acid, and this process continues to stimulate joint inflammation. Therefore, even if the uric acid is normal, the joint may still be painful. When this happens, it is recommended that:1,Continue anti-inflammatory and analgesic treatment, extend the duration of treatment or switch to other types of anti-inflammatory and analgesic drugs; 2,Reduce the dose of uric acid-lowering drugs to slow down the rate of decline of uric acid in the blood, so that the uric acid level decreases slowly. 3,You can go to the hospital for further examination to eliminate the existence of other diseases. 4,Adhere to a low purine diet, usually pay attention not to eat purine-rich food, such as animal viscera, seafood, etc.
