Hi, I'm allergic to drugs.... it all started in jan when i took a pain killer imole.. itching started with hives... after couple of weeks it vanished.. recently i got operated for piles, this time too i was given certain pain killers, and same reactions... i took avil, and citrizine, but for few days i was normal and again it started to itch and hives were forming all over the body. i stopped taking all kinds of medicine a month ago, but still hives and itching are present. although its not as intense as it was, but i'm very uncomfortable with it.. kindly help. is this a serious issue.. will i be normal again. is it life threatening??
