I have experienced a very itchy rash for now 3 months. Have seen a few doctors who said that I had shingle, staph,Pityriasis, allergy, scabies, which I received treatment for each item! I think that it might be because I take Amlodipine 2.5 . should I stop taking the blood pressure medicine and take antihistamine so that the itching goes away? All I need is a doctor like you! I am very healthy and to have this urticaria and not knowing how to get rid of it is very annoying and frustrating!! a la grĂ¢ce de Dieu! Claudine
