my tendons and ligaments were so bad that i was tearing tendons and ligaments (at the entheses where they attach to the bone). it was a serious problem. then i learned about low dose naltrexone (LDN) here.
http://www.lowdosenaltrexone.org/while it is not the cure-all, it has improved my tendon and ligament enthesitis so dramatically that i haven't torn anything in almost 3 years now since starting the drug.
other things that help the tendons and ligaments:
i take the muscle relaxant zanaflex.
the doctor put me on coQ and i put myself on magnesium for the muscles.
when the muscles aren't so tight and aren't thus pulling so much on the tendons, it gives them some relief.
the other things listed below my name help with inflammation over all, and that helps everything over all.
