I am having urticaria all over my body from last three months seeing a dermatologist from last two months but there is no improvement. Like its ok when I am taking medicine but I again get the allergy very same day when I stop taking it. She has asked me to take various tests like cbc, serum ige but I do not see result. I do not even know whether the test is useful or not. Please suggest whether should I continue with her or do I need to change doctor? Tell me the possible treatment and also tel me should I visit a dermatologist or an allergist?
