I had abdominal surgery about three weeks ago, during which I was put under anesthesia and received narcotic pain killers right afterward. Ever since I ve noticed my skin bruising super easily. I have bruises all over my legs and I don t remember running into anything or where any of them come from so I m apparently just highly more sensitive than usual. Then yesterday I started to develop a very itchy ash. Also, if I lightly scratch an unrelated itch, it turns into a rash and outside of that there is the same looking rash all over my torso. That surgery is the only thing I ve done out of the ordinary in the last several months. Could the anesthesia or narcotics have affected my body somehow??
