Thanks @triciaot. Both orthopedist and PT do not think it is a joint so not arthritis. PT doesn't know despite three months of massaging. Orthopedist seemed unsure, guessed bursitis and wanted to send me directly to pain management though offered MRI. I will get an MRI next week. He did x-rays of lumbar spine (where I already have fractures) to make sure that area wasn't the source.

ps orthopedist said x-rays are sufficient to detect or rule out cancer in bones, 95% of the time, but anecdotally I seem to read about a lot of cases where that was not true...

I am not feeling scared. I have honestly learned not to feel scared until there is a reason. I am sure you can relate. I hope you are doing well and thanks for responding!
