Hello. For about 7 weeks I have been getting hives that always seem to come about during the evening, around 7-10pm.This makes me lean towards a food allergy, but I have not changed anything in my diet or used new soaps, detergents, etc... Taking a benadryl solves the problem, unfortunately it makes me very drowsy. The hives itch, but are not too bad unless I start itching them. They also really only localize themselves to one or two areas, for example I get them on my left shoulder one day and the next near my stomach. If this was a food allergy would/should I be getting them more all over my body and second any ideas as to how I could suddenly be getting hives for no apparent reason?
Went through this many years ago just as you are, exactly. Hives would appear somewhere on my body every day. This went on for a year after living on benedryl.
Try eliminating foods; for me it was eggs; a food many are allergic to. For me it started when I took sulfa and was allergic to it. Start off with basic foods, veggies, fruits, meat, no extra seasonings, etc.
Hope this helps. Have you been on any medicines? Also, hives can just appear out of the blue for whatever reason. Your body letting you know something wasn't right I guess.
I think I might be allergic to sulfa drugs as well. I had a kidney stone for 7 weeks and the hives started about 2 weeks before my first initial attack. The hives have seemed to have gotten better but still come out. I went through benadryl, clariton and zyrtec. All worked but for me zyrtec was the best, caused the least drowsiness and got rid of the hives. One zyrtec worked for two or three days.
My hives started after I took the sulfa. I was told I was allergic to sulfa, stopped taking it, but the hives continued.
Found out that sulfa can mix with foods, particularly eggs/dairy, and cause a reaction. I had some type of egg product every day without thinking about it, espcially mayo! I think my body didn't have time to heal after stopping the sulfa; like the sulfa attached to egg? Make any sense. I stopped ALL egg products and after a few days, much better. Years later I acidentally ate something and found out afterwards that it contained an egg product, but nothing happened. I eat anything now with no problems what so ever. Lucky me. I would try to gradually introduce food again, and when you find something triggers the hives, bingo! Elimate that for awhile.
