urticaria
"I have had chronic hives for 10 years now. They started shortly after having gastric bypass surgery and have never gone away.  I was on a cocktail of allergy medications for years and they only kept the hives from getting too out of control.  I also was on an immune suppressant (that organ transplant patients take) for almost two years with very little change.  I tried acupuncture too. About two years ago my allergist approved for me to get Xolair injections.  This was the first time in 8 years where I didn't have hives at all.  An injection lasts approximately 8 weeks and then I start breaking out again.  I have had no side effects from it. I hope one day my hives will go away, but for now, this has been the ONLY medication that has worked"
