Thanks gals...I do not recall doing anything strenuous or unusual, but who knows....like when you get a giant bruise and have no recollection of getting it....
It only bothers me with pressure or certain movements. Add this to the list, along with my sternal joint pain that I still have. That is arthritic changes blamed on rads. The gift that keeps on giving....well if it cured my cancer, I will gladly take some mild discomfort!
I'll see how it goes, but I am on the books for Aug 9 with my onc, so if it is still flared up then, I will discuss with him. Could make for an interesting mammogram that day... EYOOUCCHHH!
