Owth.

I thprained my tongue.

No, it doesn't really interfere with talking, never mind typing.  This morning, it was interfering with yawning; come dinnertime, and chewing turns out to be problematic.

And I'm quite aware that it's not literally a sprain.  Whatever the problem really is, I'm sure it doesn't sound as funny, nor convey the situation as succinctly.

If symptoms persist, see your doctor.  Which I ought to be doing anyway; he's been pestering me to come in for a checkup for about two and a half years now.  I should be able to schedule that in about a fortnight, unless some new chaos breaks out.
