OK, not to worry, I'm OK. And I'm due for a physical anyway, so I'll be making an appointment with my doctor and I'll be sure to ask him when I go.
However...
Last night in the dojo, I had a sudden urge to yawn, even though I was not tired or bored. I yawned, a big huge yawn, and as I did, I felt myself start to black out. I managed to control it and I was fine, for for a second I was pretty sure I was about to hit the floor. I've passed out before in my life, so I know what it feels like - the black spots in front of your eyes, tingle in the fingertips, hearing recedes as if everyone was suddenly far away...then you hit the deck. This was just like that; except that I didn't actually pass out.
For what it's worth, this was very early in the evening; we had not even started our warmup calisthenics yet. I had been in the dojo for about a hour previously, helping out with the kid's class. I noticed I was sweating profusely, although it was not hot in the dojo like it sometimes is; it has been raining like crazy here though the last several days, so the humidity was like soup. So I figured I was sweating due to that and didn't worry about it. I didn't feel thirsty but I made myself drink some water anyway, since I was sweating so much.
When kids' class was over, we got ready for the evening adult class and while standing in line waiting to begin, that's when it happened.
Afterwards, I took it easy during calisthenics at first; we were doing some spinning back kicks which I pretty much suck at in the best of times, and I stopped because I was getting dizzy; I actually thought I was going to throw up (but didn't). Then we did some straight up hard-core exercising; one of our Senseis is into a new exercise routine called 'Insanity' (from the P90X people) and we ran some drills from that in the dojo. It was killer, but I kept up and only felt out of breath, which was totally understandable given my level of conditioning.
The rest of the evening was fine, but overall I felt kind of puny. Came home, had dinner, went to bed, all was fine this morning.
But I have never yawned and nearly passed out from it before. What's up with that? Anybody ever have anything similar happen?
