Cannot diagnose you: I'm a lab specialist. The first principle is that routine labs mean nothing in the absence of a history and physical. If your joints are more extensible than other folks, but serious disease (Ehlers Danlos IV) is not yet obvious, then it is just you and you can stop worrying. Lab reference ranges are set so that several percent of healthies fall outside. Best Rx for these worries is hard exercise.
