I am interested in the connection between my having Ehlers-Danlos Syndrome , Type 3 ( hypermobility ) and tendonitis . My son has been diagnosed with this syndrome, with subluxing shoulders like me (surgeries on both my shoulders 20 yrs. apart), and my daughter, a pianist like me, is dealing with tendonitis in the right wrist/ arm now, as am I! I DON T think it is coincidence, do you?
