I talked about my PT problem with one of my clients. He mentioned that he's going to a shoulder specialist at a different clinic. This PT did his research on shoulders when he got his doctorate in physical therapy. He's been working on shoulders for 17 years.
I called and made an appointment. His clinic is in one of those places that is so easy to bike to and a royal pain to get to by bus with lots of walking and transfers. But I can't bike there because I am not allowed to lift anything over 5 lbs. My bike weighs more than 5 lbs and in order to ride it anywhere I need to carry it down the stairs from my living room to the sidewalk. So I had to take the bus.
It was worth it. Shoulder PT gave me new exercises. Exercises that make sense. I can feel muscles stretching, and I expect to gain mobility. Shoulder PT understands the needs of yoga. He commented that my body is now where most people end up. My range of motion is close to what textbooks call normal. I demand more and he's going to help me get there.
I didn't know there were PTs who specialize in different body parts. I guess I'm going to have to learn a lot more before I get my life back.
