Hi Karen, I know the type of pain you are experiencing. When I had my second mastectomy, I required further surgery 3 weeks later due to the formation of a huge blood clot under my expander. Prior to this my surgical pain was just "normal". After this extra surgery which reuired the expander to be removed and washed out and then replaced, I experienced a real hypersensitivity to the whole area. Like you, it felt like a sun burn and really irritated. I could no longer wear my post surgical bra, and even a light T shirt was enough to thoroughly irritate it. I found some soft padding and used that to protect the area. ( I used the soft stuff that goes under a plaster cast). It helped. You will be pleased to know that this did settle down, and I have no problems at all. It seemed to take a few months to settle down, and I found massaging the scar tissue helpful. I hope you find some relief soon. You could ring your Breast Care nurse and speak with her. She will probably reassure you and explain that what you are experiencing is fairly normal, and everyone heals a bit differently, but the nerve endings should settle down soon.
