urticaria
"I've had CIU for 15 years, have been to docs from Boston to Colorado, and more cocktails of different medications on and off label.  The hives took away lots of my life!  Welts and angioedema....started xolair ten months ago.... Very few hives for several months then they were all gone.... After 5 months I came off all other antihistamines.   Now hive free!  Still get one shot once a month"
