After much conversation (nagging, lol
) my wife convinced me to try acupuncture. I, of course, always considered acupuncture to be voo doo hoo doo and was very reluctant to try it but she was very insistent if you know what I mean 
so I made an appointment with a lady that was recommended by a friend of, who else, my wife.I went in, filled out all of the paperwork, and she took me back to a very comfortable chair. We talked about the pain and diagnosis for a few minutes and I told her about the limited range in my left shoulder as well. She had me take my shirt off
and I think before I could even get set down good she had several needles in both shoulders. over all, she put in about 25 in my right and maybe 10-15 in my left. I stayed like that for about 30 minutes, almost falling asleep. When she came back in, she took out all of the needles and asked me to go through several range of motion exercises. Imagine my surprise when I could move my right arm at least 50% more without pain than when I went in and my left arm had almost 100% range of motion pain free.I went back to her for 3 additional treatments and have 100% motion in both arms and no surgery. 
Now, I will admit that I did try acupuncture for my knee before surgery and it did not work. But she told me up front that it may not due to the type of injury I had.
Sadly, my acupuncturist passed away last year and I am in search for a new one. However, I would strongly suggest at least trying it prior to letting them cut on you.
