I don't know what to tell you as I have very similar problems, really flexible but lack stability from an injury. I had crap (read army or maybe vice versa) physical therapists who old me to do rotations as wall stretches, but the last one I really liked. He is a master with needles. He didn't say go work out hard, but I am considering doing it anyway if it didn't hurt so much.
Hoping to see where this goes.
yeah, but "hey i'm Khan the sword king" is not normal.... the universe is being fickle... this is a thing... ignore me for a few weeks.
