Medical terms are weird sometimes. I had a "shoulder manipulation" where basically they put you under general anesthesia, then move your arm all around to break up scar tissue in the ligaments. It's glorified stretching that would be too painful if you're awake. Insurance considered it "surgery".
I did too. Dr was a damn quack. Woke up in recovery in all kinds of pain. Damn idiot wouldn't give me anything for awhile. Never went back, had shoulder surgery that fixed rotator cuff.
