I'm glad you're getting some tests back today that will offer a clearer indication. It does sound like there is a very, very good chance that your back pain is caused by something non-cancerous, but it's so important to rule out cancer early! My poor husband had symptoms for a year and a half that the doctors told him were nothing but which turned out to be cancer. I wish we had been more aggressive about demanding tests or that his PCP had told him to get the tests people his age are supposed to have anyway!

Very interesting, the connection between fasting and back pain. I can see how fasting would have a negative effect on electrolytes, but never would have connected that to back pain. I'm glad you have something scheduled with the specialist because that first oncologist you talked to sounds too dismissive to go back to. Have you ever done one of those Ancestry DNA tests and run the results through something like Promethease? Seeing my genetic risk (combined with known family history) pushed me over the edge to get a biopsy instead of waiting and watching for six months.

Scanxiety sucks big time and it is very hard to find support when you are worried about an initial diagnosis. Fingers crossed cancer is ruled out for you today.
