I have taken my daughter to SEVERAL Dr. since Sept. 08 for chronic hives. We can not make it longer than 3 weeks without a massive outbreak. Each outbreak is worse and none of the Dr's can figure out what to do. We have missed over 20 days of school. tons of test with not anwsers. xyzal and Zantac was working but she has had 2 seperate reactions in 4 days. She is on Atarax now since she has the symptoms. No food allergies, and no enviromantal allergies. What is wrong and what can I do to help her?
