Hello, I am female 26. last year i had a 2 week session of dermographism in end of september. it passed away itself. this year again it has come up. it last during the day , coming up time to time and lasting about 30-40 minutes. I did a full blood test, ,THYROID TEST, LIVER AND KIDNEY TEST and all were good. i also did a IGE blood , it came out the result of 578ui/ml. EVEN I DRINK ANTI ALLERGIC DRUGS, it doesnt really have a big effect on them. when the flares comes up , mostly and face, ears, neck , sometimes tummy, they rarely are itchy and also give me shortness of breath and headaches. What to do ?
