I had 2 rotator cuff surgeries in the last seven months. My last one was on June 18th. My surgeon put me in a sling for only four weeks this time, instead of eight weeks like my first surgery. Some how the sutures completely tore off, and he said it was still tied and the knots didnt come loose. I started therapy, but still have a good amount of pain. My question is, is it really that easy to re-tear the muscle or does it take major heaving lifting or movement to tear it? I hope to get another MRI in the next month or so and hope to god it's not tore again. I really do not want or need to go through this crap a third time in less than a year. Thanks, The one armed bandit.
