YWCS, I've been most of my work with a pole for about a year now. I've had lots of problems, but touch wood things are better now. I got a lot of pain between my shoulder blades and acquired two tennis elbows. In the end I got a cortisone injection for one of them. Much better now. However, this is what I think I was doing wrong. I held the butt of the pole around waist hight and moved it up and down from there. I tried to use my legs to rock, but found I was only doing this on high windows. Downstairs was all arms. Now I try to extend my arms to their full length downwards. So now the butt of the pole is around half way down my thighs. Seems to help me. Good luck. Also I claim massage therapist as an expense, and don't doubt about it being kosher.
