Good physical therapy is the key. I tore my cuff, waited six months til I finally went to a doctor for a frozen shoulder. No surgery needed since it healed during the six months. But I needed a PT that didn't mind causing me some pain.

The PTA's didn't like causing pain, but when the PT got me on the table and stretched my muscles for my cuff till I felt a snap.... very much like a bunch of rubber bands stuck together in the middle and coming apart when stretched. Then there was noticeable improvement and no lingering pain.

I wasn't 100 percent after the first time I felt the muscle groups come apart. But three such events and I was and still am 100 percent movement and no pains that are not just old age. Don't discount all the menial things they have you do in physical therapy. They all work to get you to that point.

My tear likely was not as bad as yours. I only went to about six or eight weeks, three times a week. It's didn't keep me off the bike.
