GRIP MYSTERY

My right hand hurts when I clench it on something. What has occurred. I did play a show last night in Sacramento, and my right hand was involved for bow-holding reasons, but I don't think that's it.* Was it all the Boom Blox I've been playing? That's probably why my elbow's a little gimpy, but not my hand. I'm going to blame 9/11.

* I experimented by holding a pen in the manner of a bow and playing a ghost violin; nothing disastrous happened.
