I'm no doctor or don't pretend to know everything but from my own pain experience and listening to other pain/cancer survivors they say bone pain and treatments go together. Hurrah for the good bone scan!!!!! Have they mentioned arthritis that's often the cause of bone pain as I've been told, but I have met many pts at cancer support group meeting say the doctors told them for years it was arthritis but then the old cancer rascal cells showed up and guess what bone cancer mastastic spell? Tamoxifen fog, anyway I try to research for my doctors since they all need skates to keep up with their schedules. Carol K
