Itchy Rash after Surgery

I am having same delayed reaction as you. Benadryl pills don't help. I'm itching and have the red bumps all over my abdomen area. What relief is there besides ice packs? What did you get to stop the itching ?My surgeon said to take Benadryl pills because I'm probably reacting to the surgical prep. The itching is driving me crazy. Any advice you can give me will be much appreciated. Thanks, Sheri

Any help ?
