Have you ever been tested for Ehlers-Danlos Syndrome or similar connective tissue diseases? A lot of the time with rare diseases, you can go quite a while between doctors that have even heard of the disease, and come up with a course of treatment that actually would be useful. Chronic sprains and other tendon injuries are a pretty classic sign of the disease, and there are definite exercises you can do to help mitigate effects, but because a lot of the exercises are counterintuitive, developing a course of action that actually works is difficult.
