I saw my doctor last Monday because I thought I the rash that had popped up suddenly on my left breast was inflammatory breast cancer. She laughed a little and gave me a steroid cream to put on it saying it would be gone in a couple days. The rash is still there and all of the sudden 3 days ago I woke up and couldn't hardly move my neck on the left side. Today the rash is still there and my neck should and chest are so sore it's almost unbearable. I have taken muscle relaxers, pain pills, a heating pad and not a bit of relief. Should I be more than a little concerned? Please help!
