I have had urticaria since October last year but find it is now getting wore. Welts all over my body arms and legs and itchy as all he'll. have been taking telecast 180mg every morning but I am getting severe breakthrough and wake in the middle of the night trying not to scratch, to no avail. Had an episode with prawn or u am guessing that. I had them for tea and later that night my whole mouth are tingled and swelled. Is it possible that's some of the problem or am I clutching at straws. I really need to treat the cause not the problem if I only knew what it is!
