It's still raining and I'm on holiday break, and the shopping is done and wrapped ---- So, I Googled "rotator cuff tear" + exercise and found this:
Aid My Rotator Cuff
The statements and reviews are impressive. The statement that physiotherapy should begin only when pain subsides, concerns me (my PT began while still in pain, and pain persists). It seems both believable and unbelievable at the same time.
The heat wrap, cold wrap, and ultrasound tool are an expensive investment (though not nearly as expensive as PT and surgery) but come with a 60-day money back guarantee -- and they can be used over and over again.
