I'm afraid I can't add much to what your dermatologist has already done and, presumably, said.  There are no diseases with which I am familiar which cause itchiness of the kind and intensity you describe.  In particular, allergic reactions don't do this kind of thing.  My advice would be to apply a topical anesthetic (Sarna, Prax, Benadryl) liberally and often on the areas when they itch, so you'll be better able to leave them alone.  Sorry I can't be more specific.  

Best.
