Hi P.T.,
Perhaps you should have started a new thread but no matter...
To my knowledge,Frozen shoulder is a self limiting condition which doesn't really get better until it wants to despite all the treatments in the world...
I usually advise my patients to wait until the stiffness starts to get better and then see me about the shoulder. Until then, it is maily symptomatic treatment that you will be giving (which doesn't sound like it is working).
