could be referred (from your spine) osteoarthritis pain. Something could be impinging on a nerve and you are feeling it elsewhere. Pretty common. Finding a good acupuncturist -- or going to an acupuncture college where they spend a lot of time for cheap is a good idea. Also, an MFR therapist would be helpful. They will manipulate your spine so it is correctly positioned in your body, and you can see if it helps. Sometimes muscles move as units as we age and tug on things, causing pain. Could be pressure on your gallbladder, pancreas, appendix, or spleen. I think (IMHO) an acupuncturist is a much better idea than a chiropractor, for sure. If you think it's a skeletal issue, see an OD or orthopedist and get referred. My OD did chiropractic manipulations/adjustments as well.
