Suggest Cure For Rash And Soreness In The Leg & Groin Area

Hi. I had a ct scan yesterday and last night I had a red rash and soreness on the inner right groin area of right leg and also rash on right calf and around to shin area. I had a barium enema, and an omnipaque 300 injection prior to scan. The areas are a little sore to the touch, also.
