gouty arthritis
"I have taken off/on for several years, no problem, but recently I took because I had Crab meat and than few days later a hamburger; I don't these very often because of gout.  I took the medicine for the crab meat and awoke with severe itching in my hands and some swelling.  When I had the hamburger I again took the medicine, this time not only did my hands itch and swell; my entire body did, including my tongue.  Apparently I can never take this medicine again, just have to stay away from any of the foods on the no-no list."
