Hello! I have been experiencing moderately severe itching, mostly later in the day, with the tops of my feet, inside of my arms, tops of hands, back andscalp. When I scratch, it gets worse and leaves red streaks and bumps appear that look almost like blisters. If I apply anti-itch cream, it helps. Also, I am taking about 50-100 milligrams of Benadryl a day, and found that ibuprofen also helps quite a bit. This has been going on for about six weeks. I have made no medicine or dietary or soap, deodorant changes etc. Any suggestions?
