Hello, my brother is 32 years old and he has been having problems with his foot specially his right one for a long time and he has been diagnosed with "Gout" and has been taking medications as such. But recently he was told his uric acid level to be normal on repetitive different tests. His foot pain is intermittent associated with swelling ;sometimes it's bilaterally and he can't stand too long or walk since the pain is severe and once it started it's persistent,so please tell me what it could
