Frozen shoulder?

UPDATE–thanks everyone for your helpful comments. I saw my GP, then this morning saw a physical therapist, worth her weight in gold I might add. I feel loosened up already, and she gave me some good exercises, and I’ll see her again for more treatment. Then, I have a friend who is a yoga teacher who had frozen shoulder and found ways to work with it, so she is going to do a special session for me. I also really like the sound of the ART (active release technique) and may give that a try. Thanks again to everyone. Melitta
