Hi, I am a 17 year old female and ever since i was 15, i 've been getting itchy, burning welts all over my body. My dr had said that it was physical urticaria or dermagraphism. I have been taking certirizine thats been keeping them at bay, but even if i take an allergen, they still pop up if i am hit/scratched. Sometimes they won't go away for hours... i just want to find something that i can take to get rid of them.
