Severe itching and prickly feeling in upper arms. An_223991 posted: At the end of August, I began having a severe itching and light pink/red rash on just my upper arms. My Dr. has given me a cortisone shot, Zovirax (thinking it might be shingles) which caused me to have migraines. I've tried Calamine lotion, Aveeno, Benadryl, etc and got no relief! I googled severe itching in the upper arms and found alot of people with this condition but no answer!
