i have had severe itcing on my shoulders and upper arms for about 4 months. i have been to a dermatologist who said i had an allergic reaction to the sun, but that was 3 months ago. i am tormented with this itch, have tried several cortizone creams, benadryl and prescr.pill for itching. i have a little bit of a rash, but not much. my skin gets blotchy red, but that could be from the scratching. i am tormented day and night, with no relief. anyone else with this problem?? i would be so thankful for any suggestions.
