I have had two frozen shoulders. One of them required surgery to vacuum out the "crud" as my doc (a sports medicine specialist by the way) put it.
After the surgery, I must have tried four or five different physcial therapists over a period of about two years. None of them really did any good and some actually made it worse.
After the failures, I was beginning to feel it would never be normal again, but I agreed to try therapy one more time. This time, it took exactly three weeks to give me most of my range back. The therapist knew exactly what she was doing (it was in a major hospital PT department) and recognized that I would put up with a lot to get better. She worked my shoulder slightly differently than anyone had before and until I had had enough and it was feeling inflamed, then she iced me down. YAY...at long last--SUCCESS!
When my other shoulder began to hurt, I launched into my own program. I began to walk my fingers up the shower wall in the mornings under a hot shower--a little higher each day. I stretched it every way I could and refused to favor it. After about a month, it went away.
Two points:
Don't give up on physical therapy, but do switch therapists if you are not seeing any improvement.
If you feel it happening again, you now know how to prevent it. Do the exercises, stretch and rotate. Being under a hot shower helps. DO NOT FAVOR YOUR SHOULDER JUST BECAUSE OF PAIN. Be tough or it will nab you again and in my opinion, it just isn't worth having it twice
