I had my right shoulder replaced last week. I am home recovering. I started taking tramadol for pain when I was in the hospital. I have no experience taking this drug. I started itching a little in the hospital. They changed the bandage and removed the drain. I came home and the skin around the new bandage became red and itchy. I then developed a rash under my arm. I wanted to scratch it but could reach that area. I took my ice packs and laid them on the rash. Could I be having a reaction to the bandage tape? I removed the bandages. My husband rubbed lotion on the rash under my arm to calm it down. A nurse came by for follow-up and looked at it. She said it did not look angry . The rash is driving me crazy. I read about side effects when you take tramadol. I am trying to see if that is what happening. What do you think?
