Suggest Treatment For Jaw Pain Without Chewing

I'm 26, 150 lbs., and no history of medical issues. I'm experiencing pain in my jaw when I taste food or drink, even without chewing. For example, I can drink through a straw, but the moment the liquid touches my tongue my jaw feels like it is being electrocuted. This began two days ago, and I'm reluctant to eat even when very hungry because it's so uncomfortable. What's going on?
