Torn Rotator Cuff?

[BlackDog]

Have any of you had to deal with a torn rotator cuff in your shoulder? I've been diagnosed with a 50% tear in my super spinatus (sp?) muscle in my right shoulder. I had an MRI last week, and the doc gave me a cortisone shot today. The doc wants me to do 6 weeks of physical therapy twice weekly, and hopefully that will improve the situation enough to avoid surgery. For those of you who have had this, how did the recovery go? Did you recover full overhead use of your shoulder? This is the arm I fly cast with, and as it is now it would be painful to fish for a day. Thanks!
