I've had severe, frequently recurring tendonitis problems in my left hand and my right shoulder/uper arm for the last couple of years. It got so bad that I couldn't play the banjo or guitar for months on end. I tried a regimen of physical therapy and that helped some. But the healing really took off when I combined the PT with a daily dose of Glucosamine. Since then, my hand has had no problems at all and the mobility in my shoulder is making great progress. I'm a believer!
Rick, I'm also interested in finding out more about your A,C&C. My parner, Amy suffers from headaches frequently and if this helped you it might help her.
