So, it turns out that I somehow have a stone in my saliva gland, and the swelling was from backed up saliva. Yucky.

But all I have to do is suck on some lemons, to generate enough spit force to push the stone out. If that doesn't work I'll have to get it probed (which will be painful, I can imagine), but I'm hopeful about the lemon solution.

So, goodbye to my sense of taste for a while.

Wish me luck!
