No diagnosis, only mild symptoms.
My hips, fingers and knees are way too flexible. I could bend my knees the wrong way as a kid and walk like a chicken. And my fingers bend most of the way backward in a curve. But I have a lucky ace in the hole. I have a hyper-aware brain (call it ADHD, autism, I don't care what you call it. I feel every wrinkle in my clothes all day long) so I've had no serious problems. My gait is always over-thought and conscious. I figured out in my teens that having my toes pointed out was probably hurting my knees. Within two weeks I had retrained my feet to point perfectly forward with every step. Knee pain greatly reduced after that. So I guess I'm unlucky enough to - SQUIRREL!!! - but lucky enough to - ow, that hurt, I can stop doing that. It's self-limiting thanks to my hyper-awareness.
