a shot of prednisone would probably work wonders for the itching and swelling! tell him to get his itchy self to the doctor!! I have a major itchy rash over my legs and tummy because of my pups (pregnancy rash) and I found that the prescription strength hydrocortisone worked MUCH better than the OTC strength. Claritin might also help and is available OTC, but it about $10 for a box of 8 pills or so...
