Hives are the most perplexing things to ever get and I feel your pain. My mother used to get horrible hives and found out it was from preservatives in cold cuts, wine and cheese combinations. My mother-in-law also had hives just before I married her son and her doctor said that they will disappear as quickly as they came. She had them for 2 years! Check your diet and see how many preservatives are in the foods that you are eating. Cut them out and you might find relief. Benadryl is suppose to relieve the horrible itching. Cool baths also help alot. Hope you soon find relief!
