On September 27th I received the senior dose of the flu vaccine. Within a day I experienced mild cold symptoms and an outbreak of hives. These are not rash like, but more like insect bites that are hard and lumpy. Initially my physician told me to take Benadryl 25 mg. twice a day for two days. I did that. But the hives just keep appearing on my arms,legs, feet and face. It has been more than two weeks and they have not abated. I put cortisone cram on then to calm the itching. But they are still coming pout. My question is: is they a permanent condition. Are nuts, strawberries and eggs foods I need to avoid?
