Last night I was practicing and all of a sudden I got this unbelievably painful cramp under my jaw, just behind my chin. It happened while I was stretching my chops a bit after some long tones that I had been playing. Has anyone else ever experienced this? I have gotten minor cramps in the same place before, and even in my tongue, but never to this level. This was a full out charlie horse type of a cramp that brought tears to my eyes and it was a full 5 minutes or so before it loosened up to the point where I could continue practicing. It's still a bit sore today. Earlier in the evening I was eating salted-in-the-shell sunflower seeds at my daughter's baseball game and I wonder if that had anything to do with it. Comments?
