A long time ago (10+ years) I got tennis elbow from using the mouse on my computer. Since I started college online, I have some other kind of -elbow, involving tendonitis on the outside of the elbow. (It's from using the touchpad on my laptop with my middle finger instead of a mouse.)

It really hurts when I ride sometimes, and my grip is useless and I can't twist like you said. But, I finally found the tennis elbow strap I was given way back and after wearing it for a couple of days, my arm feels GREAT and strong with the support. Maybe you should try one. They're available at the drugstore.
