pain in my jaw

Yesterday after my bike ride, my jaw started hurting. Today, it's just constantly in pain, and if I move it wrong, I feel a stabbing shot of pain. Fabulous. So, I'm at home, being irritated because I could just as easily be at work if I could make it there in a car (but I feel every bump, and they hurt). I might've even worked through that pain to get to work, but then I also can't really talk, so I wouldn't be a very effective advisor today anyway. SO ANNOYING.
