I know you have already gone to the doctor...here a few suggestions tho...I took Atarax for a while in the 70's for dermatographism (hives)when my parents got divorced. I have also had cold hives and successfully used the homeopathic natrum mur. Medicine worked good but eventually wanted off. I found the book Body Mind and the B Vitamins and started taking about 100mg profile of B's plus C which are for nerve health...you can go up to 150 mg. Profile. Got off the Atarax. There is a homeopathic histamine that you could take in 30x or 200x and keep on hand. Under the tongue it works within minutes. Also, for relief colloidal oatmeal baths are very soothing. Skin conditioners are very hard to treat...even for doctors. Get your vitamin d levels up and take K...you will see improvement. We have very similar skin conditions and itching is the thing I hate most in the world. Good luck...
