  Time for a self health diagnosis. Everytime I bite down, the left side of my jaw snaps (? ), cracks (?)..... pops! Yes that's it. And when I open my mouth widely, it hurts tremendously. That can't be good, can it? It's kind of weird, yes fasinating. It hurts evertime I do it, yet continue to do so just because it amazes me how weird, and how much it hurts each time I do it. I really should stop.....really should.......
