Can a gout attack on knees eventhough uric acid level is normal? what should i do? i had a history of gout.

Yes it can/keep Tx.,: Yes it can happen. Many gout attacks occur even when the blood uric acid is at normal levels. This is often the sign of an attack or an impending attack. The best thing to do is continue therapy and keep on doing things like eating a balanced diet, losing weight and avoiding triggers like a lot of red meat and alcohol that can cause a flare up and see your doctor if there's still lots if pain.

Yes, it can: In acute phase, uric acid levels drop due to increased fractional excretion of uric acid, and so normal ua levels during an acute flair should be expected when evaluating a patient during such flares. If aspiration of an affected joint or tophi is not feasible, repeat ua levels should be sought weeks after the attack is over. www.med.ucla.edu/modules/wfsection/article.php?articleid=475 best wishes and happy new year.
