I had surgery for appendicitis about a month ago. I don t have a history of allergic skin reactions. About 3 days ago I got an itchy, slightly burning red, splotchy rash on my lower legs (calves and shins), forearms, and a smaller rash on my lower chest. The rash sometimes looks and feels a bit like heat rash or poison oak, but there doesn t appear to be any weeping or bleeding unless I scratch. I did email my doctor but was wondering if anyone was familiar with (or had seen cases of) something like this. Thanks!
