My severe hypermobility causing lots of problems, what kind of doctor should i see?

Orthopaedic surgeon: Orthopaedic surgeons commonly deal with hypermobile joints, especially if the involved joints are chronically unstable despite adequate attempts to stabilize the joints with physical therapy, strengthening and functional training.

Rheum and PMR: Hypermobility is usually best treated by an exercise program focusing on improving proprioception, dynamic control of joint movement, and aerobic capacity. There is a very limited role for surgery in most typical cases of hypermobility, especially in adults. A Rheumatologist would be helpful to rule out more worrisome causes of hypermobility and a PM&R doc could assist with symptom management.
