Dear Tracy,
A the otehr member said, it takes a time till the Wikipedia reference-linkfrozen shoulder gets better, it can be from 1 year to 10 years...but most likely wont be more than 1 year.
I find acupunture very very helpfull, mainly for the muscle tightness, and apin. Ans if the pain is gone, movement would be easier.
Depends on the state, pasive mobilisation (that ur pohysio does) or a good exercises plan would be best.
Can I ask, how was the onset of it? could u give soem more details?

Greetings
