Jerry....my doctor refuses to discuss that my shoulder problem might be from playing the piano too hard with my left hand. Hence, I'm left with trying to self-diagnosis.
I'm unable to download the PDF. I'll have to go to the library to do it. But, is that about the "resistance band exercises?" My instinct tells me I can get some real benefit from stretching and corrective exercises.
For anyone reading this, my doctor DID explain about "inflammation" of the entire body causing the pain. I notice when I take my prescribed "anti-inflammatory" medication the pain subsides.
I did read a lot about "inflammation" on the Internet. It's something I was never aware of. It comes from stress, old age, improper nutrition, etc. You might want to look at that.
