HI Dr. I recently had pain in fingers with swelling and redness at the figure joint adjacent to thumb. Afer consulting Dr. he identified it as a possible gout attack. I did all the blood test which were normal and uric acid was 6.6. So I was put on febuxostat for 15 days. When I was on 9 th day of treatment I had more pain. So I stopped it. Then I controlled my diet last week uric acid level was 4.5 just by diet control now last night I started getting pain in one knee. On left ligament side and today in hand elbow? what can be the reason for this? what should I do?
