So glad to know you are finally getting to see a rheumatologist. I'm sure that will be helpful to you. My PMR is currently in remission. The rheumatologist advised me to avoid strenuous exercise, especially stair climbing. That is not possible since I live in a house with four floors. I still have some residual pain and stiffness in my shoulders, buttocks, and thighs, but off of prednisone and over all good for a seventy-six year old person. I can relate to the jaw pain. When my PMR was active, there were times when I could not open my mouth to eat; it was too painful. I wish you good luck at your appointment with the rheumatologist and I hope you will update your treatment and progress.
