Playing last night, and, about halfway through one of the later songs, all of a sudden I got a severe pain in my right (plucking) index finger and forearm. Had to stop playing. Came back in with the vocals, and started hammering on the roots so that there'd be some bass, and limped to the end of the song that way. Stretched it out and tried again, no good. Finished the night using second and third fingers only. At first, even that set it off again, but it got better. I figure it was just a cramp, but this is a new thing for me. I also know that I have a tendency to overreact to things like this, but, if this keeps happening, or gets worse, I might have to quit playing. One positive thing: I got a good joke out of it. I stepped up to the mic and said, "Really, this has never happened to me before. Really." And every woman in the place smiled and nodded, obviously thinking, "Yeah, I've heard that before!" Anyway, the finger aches this morning, but seems to be working all right. I hope that's the end of it.
