it's a very slow acting disease...it seems to attract itself towards injuries. In other words if you get a fracture, break, bone spur, or anything of the sort the disease will head that way and replace with fibrous tissue for what should be by bone. You can get a better depiction with Xrays. Try getting FB Xrays done and they tend to be cheaper at a chiropractic clinic. Chiropractors deal a lot with bone functions, diseases, issues, and defects. You can try finding a good one.
My suggestion is increasing your calcium,potassium, and magnesium intake. Calcium preferably the other two just sustain muscle fibers to where they are relaxed and not straining ligaments and tendons (Tendons are muscle to bone and ligaments are bone to bone tissues).
The biggest thing is not to strain yourself which is a good excuse for not having to lift a lot. You will only end up in a chair is you strain yourself and cause injury which will only be healed by the more "rubbery" fibers. Best bet is occassional chiropractic, massage visits (not needed weekly but enough to keep you balanced) which I hope your insurance can cover (I know what insurances cover both) or you can get Doctor prescription for those 2. Making sure you have TONS of Glucosamine and CAlcium is ideal to make sure your bones are strong so they won't be hurt and replaced by fiber tissue.
