Hello and welcome to the OCF forums.
I completely agree with Cheryl and Christine. Your situation requires immediate attention by your surgeon. I am also in favor of a second opinion. It seems like chemo and rads would have been part of your treatment plan, but I don't know your whole story, nor am I a doctor.
I hope that you are able to find the best medical team near you. Sometimes these complications happen, although very unfortunately. Here's to hoping that it's something that can be reconstructed so that your function may be restored. First the doctors save your life, then they restore function, and then they consider cosmetics last, if that is an issue.
I wish you the best of luck. Please come back for support and to keep us posted as you are able.
Take care,
Kerri
