According to my chiro (and it seems to be supported by the article I liked to) the problem is usually caused by flecks of calcium floating around in one of the canals and bumping into things. Her treatment is to manipulate the position of my head to get the particles to roll out to where it won't cause the problem. The catch is that I can't bend over and I have to sleep sitting up for a couple of days to keep the particle from just rolling back in.

I'm going to go in on Wednesday to have her try it out. I'll let you know how it works.
