I'm glad you scheduled the surgery. I hope yours is as successful as mine was. I had only mid level aching for some weeks after the surgery, which actually felt better to me than the pre-op nagging arthritis pain I felt constantly day and night. I never experienced any of the overwhelming surgical pain that some mention, don't know what types of nerve blocks or anesthesia were used. It took 3-4 months of daily stretch routines to get my vertical reach equal to my non-surgical arm. My rTSR feels so natural that I am not aware of it most of the time, and need to remind myself often to let the non-TSR arm take more weight when dealing with heavy objects.

I am not one to rush into any kind of surgery. I had a frozen shoulder without pain on that arm a couple of years earlier, with PT I got back to 80% mobility, but that did not last. A year later, along with loss of reach to my head for washing or combing, I also developed the constant arthritis pain and could no long pick up a fry pan or coffee pot with my right hand alone.
I've been an active outdoor person, have a large vegetable garden and enjoy kayaking, so a bad shoulder was limiting enjoyment of my normal activities. I think I waited the right amount of time to have my surgery and had good results.
