urticaria
"I have been battling with hives on and off for almost 15 years. I went to see my local allergist and he said if antihistamines are not working, change your lifestyle such as diet, hair products etc. I gave hope and one day I started looking again as my hives were out of control. Got a second opinion from another allergist and he put me on Xolair. I have received my first shot last week and I haven't had any hives since then. My face is clear and knock on wood hope it stays this way. Such a relief. If you have tried everything and nothing has worked which was my situation, give xolair a shot. Its expensive if you don't have insurance but if you do have insurance, I would suggest giving a try."
