NurseBetty, anything is possible. That being said if you are dislocating and are hypermobile that is a big clue to look at EDS and see a geneticist. I was diagnosed with EDs and have never had a full dislocation that I know of. Lots of subluxations and popping things back in, but from the little you wrote EDs sounds plausible. People can have EDS and be relatively unaffected until something triggers their body (cue the mast cells).
