Talking to many people who have had many different surgeries what I hear is the worst as far as pain, and the one that takes the longest to rehab from is rotator cuff surgury.

One of my very good friends, a retired Marine who got blo hit read bad in Vietnam, did 19 month in a Navel hospital, and over thhhe curse of that nineteen months had over 20 surguries before being retired medicaly.

He year later blow out his rotator cuff bowling, and had it fixed. He told me that was the most painful surgury, and rehab he ever when threw,
