After not much success with a normal physio I went to a Golf swing/arm specialist physio and he does dry needling.

Because my whole shoulder so extremly frozen and incapible of moving well (and nerve damage) it was extremely painful. It brought tears to my eyes. He was very careful about my screws and plate and swabbed that area with iodine before he put nedles in.

But the results. There was no way that using a pulley, or walking my fingers up the wall was going to restore function in my arm. I was able to get over a few weeks my shoulder moving and my arm (with help) to lift above my shoulder. He also released my elbow which had been badly spained and by being in a sling for 6 weeks, I was unable to striaghten or move.

For the right reasons I think dry needling is worth every bit of pain. Basically my muscles and nerves had forgotten how to function and the needles awakened them again.
