More experience than I would like!
In 2004 I had my left rotator cuff surgically repaired, a complete tear that was according to my physician a very bad tear. Initial 3 months p/t 2-3 x week, then 3 months roughly 1xweek. I recovered fully, but 6 years later am not happy with the scar tissue, pains, etc.
However, I am much less happy with my presently torn Right rotator cuff. I tore it in a skiing accident in 2006. An mri confirmed a complete tear, although the ortho doc (same one that did my left repair) said it didn't appear to be as bad as my left.
It should tell you something about the pain, the rehab and the end result of my left repair that I have not done my right.
I truly am not saying that 'cause I'm suggesting that for you, I'm not. But, knowing what I know now about end result I'm not doing it until I have to. I do exercises, yoga, weight training all which keep my right shoulder in as good a shape as it can be, given the tear. Occasionally I have fairly bad pain but it generally goes away within a week.
Also, I had a great physician, does many, many surgeries on star college athletes, so he knew his stuff. At my age, 55, and with scar tissue, arthritis, and the fact that on some days my repaired shoulder hurts worse than my still torn one, that keeps me out of the O.R.
Again, you're different, just my 2 cents.
Good Luck,
Susan
