My rash started late at night on surgery day high on the chest under each collar bone with a curved line of itchiness connecting the two spots. The nurse in charge and two nurse aides told me that they didn't see anything, but said that one of the alleged spots was near the site of the epidural connector. I think that's what they said - I was on drugs at the time(!). However, hubby says that when he visited me after recovery that first afternoon, my rear end -- immodestly revealed to all the world by my open gown -- was a bright pink. The next day, the itchiness spread over my shoulders, down both arms, down my back, over my rear, and down my thighs. Like you, the rash seemed to stop there and was not on my lower legs. I even suspected the paper protective mat on the bed, although my front was affected as well. Fearing such a possibility, I had brought some prescription ointment which my allergy PA had previously recommended, but the hospital staff was extremely reluctant to use/apply anything, which they had not themselves prescribed. My favorite nurse's aide applied this ointment to my back, rear, and thighs on the last evening, which provided some relief. As she did it, she said, "Shhh!" like we were two conspirators. After discharge, I contacted my OS, PCP, and allergy PA about the initial problem and when the hives suddenly appeared, got off the oxy and onto the prednisone and OTC allergy meds, and applied the ointment (sparingly as recommended) to my itchy areas. The hives started fading from bright pink to beige almost immediately, and I was finally able to concentrate on my knees, which were feeling somewhat neglected.
Say hello to Rick for me. You are ready to roll.
