I had a bone scan last October or so. It was a free health check from the city I live in. The wife took me there, and we both had our bone density checked, along with teeth, stress level (I was a basket-case by then), and free consultation with a surgeon for my shoulder (who said at this time, getting surgery might be worse than if it were done right away!!).
My bone density was actually just a little below the norm for my age, and I also was given calcium to improve it. The wife actually was giving me calcium way before that, anyway!
Considering my shoulder injury, I thought I would have broken the collar bone, rather than sever the tendon connecting it (at least by breaking the collar bone, I'd get surgery done on it!! And, either way it'd probably hurt the same!)
But my major concern was in regards to how my joints were hurting, and I thought that was malnutrition-related, and perhaps a lack of calcium, among other important nurishments. My knees still hurt, but I think there's a slight improvement.
