Welcome, @marshelle. Oh yes, I believe @jonezzi and @4me, who also have experience with myxofibrosarcoma, know about feeling any ache or pain and the worry that it may be the cancer returning. It's a common fear among all cancer patients. @hopeful33250 has had her cancer return three times. I can imagine you and your husband are worried and the next 2 weeks will feel long.

Back pain of course can be caused by a thousand different things from exercise, raking leaves or even from immobility and not moving. Has your husband done anything new (or been inactive) that might cause back pain? Is it new?

Have you considered calling to let your oncologist know about the pain? She/He may wish to investigate or expand the order for the CT scan to include the back.
