Hi, i have hives all over my body. They have been there for over 5 months, and they are INCREDIBLY itchy. I have been perscribed 3 different antihistamines, by a consultant. Neoclarityn, levocetirizine and phenergan. Im at the the end of my second week taken them and there has been no change. The 3 different doctors and consultant each seem to think its something different. What should i do?? Any help would be greatful, im becoming desperate. Brenda
