It really does stink @cranky_granny when you can't get a difinitive answer on things.
I've had back and hip pain since starting Tamoxifen 2.5yrs ago.. Same as you, there was no sign of arthritis or anything in the original staging CT or the many follow up scans I have had.
Fast forward to May this year and apparently there are "mild degenerative changes" creeping in according to xray and u/s.
The pain continued to get worse so I have had an MRI two weeks ago.
So in a relatively short period of time there is now "endplate odema, bilateral sacroiliac odema, thoracolumbar spondylosis (whatever the heck that is) a couple of bulging discs plus a few other bits and pieces of "degenerative changes.
Anyhoo, I was reading an article recently and it was saying that hormone therapy and induced menopause can age your body 6-8% faster than normal and exacerbates any minor dodgy bits you already had.
Maybe ask for an MRI, you'll probably have to pay for it, but at least they tend to be a lot more specific than the rest of the scans and might provide some more definite answers.
Hoping you get it sorted soon lovely.
