A rheumatologist or geneticist would be able to diagnose you. I just found out that I have a type of joint hypermobility between EDS type 3 and Benign Joint Hypermobilty Syndrome. My other family members should more like you. I ended up getting POTS and then cascade of other medical conditions. I am really sick, but not from the joint hypermobility. The joint hypermobility issues just causes joint pain and it can he harder some days to weight lift. My joints give out before my muscles.
