Suggest Treatment For Hives, Soreness In Joints And Fever

Hello, I have had bouts with hives for the past few years I seem to get them about twice a year. I have seen 3 allergists and 2 primary care Physicians. They all seem to feel it's something I eat. However I am having them now and there is something real different this time. All my joints are very very sore. And I seem to have a fever every night but it breaks in a few hours. This time I didn't get any swelling in my mouth or tongue? Any advice?
