I had my 3rd breast recontruction about 3 weeks ago, after having a double prophylactic mastectomy last August. I developed a rash on my chest right after surgery, and it continues to get worse, and is not heading up to my shoulder area. I have tried quite a few things. any suggestions? IT is red, small and large bumps when scratched or washed break open and then scab over, but they are not blisters. And they are very itchy!
