@knuckled: First post - I signed up partly because of subjects like this. Double-jointed is a misnomer and misleadingly benign. It can prevent injury in some cases, but for most people it increases the overall risk of injury. It probably has contributed to a few chronic injuries of mine. I have faulty connective tissue and encourage anyone who is very hypermobile or somewhat hypermobile and already in pain to seriously look into the matter. I crack, yes, and was wondering if my body weirdness primed me to do for relief. what do you mean "misnomer"?
