I had it last year, on the outerside of my left foot. It hurt so bad I thought it was broken. Got on Allopurinol for awhile, cut back on drinking and increased my water intake daily, and haven't had it since. I stopped taking the Allopurinol about 3 or 4 months ago and it has been good. When I did some reading on it, water intake seemed to be a helping factor for alot of folks.
Beer
Beef
Seafood
Are just a few they say is high in purines. Thats what raises your uric acid level.
Hope you get it figured out, that s*** hurts like hell.
