urticaria
"Hives out of no where 4 years ago. Severe angioedema as well. 6 antihistamines a day, prescriptions, Tagamet acupuncture etc etc etc....4 years of being covered in hives every single day. Gave up on medicine.... And then decided one more try.  My immunologist said Xolair and I had my first shot exactly a week ago today and haven't had a hive for two days!   I had just one or two for The first few days after the shot   The shot did make me lethargic for a few days but that has passed"
