Foot Vibrations

My foot is buzzing. At least, that's how I described it to my husband last night after half a day of enduring it. It started yesterday afternoon. I suddenly felt this strange vibrating sensation. I thought my foot had slid causing my sock to rub on my shoe for a brief, vibrating, moment. As I tuned into what was happening I quickly ruled out the sock on shoe action and began thinking that it was occurring with my pulse.

Ehhhhh (that is my attempt at writing a buzzing feeling)! Ehhhhhhhh! Ehhhhhhh! (pause) Ehhhh! Eh. EHHHHHH!

Nope. Not my pulse. Unless, of course, I have an erratic heartbeat that I've never noticed before.
I stood. Ehhhhhhh! I walked. I didn't feel it when I was walking. I stopped. Ehhhhhhh! "What the heck is that?" I was annoyed.

By the time I laid down to work on my Bible study and then fall into blissful and much needed sleep I was beside myself. As long as I kept my foot moving it didn't buzz. Or, at least, I couldn't feel it. When Troy came up I was almost in tears. "It doesn't hurt," I told him, "but it is SO annoying. I'm never going to be able to fall asleep." As I laid there I began to wonder if I would ever sleep again. And then...it stopped. I slept. I woke up. I thought about my foot. No obnoxious buzzing. I stood up. Nothing. I walked into the bathroom.

Ehhhhhh!

NOOOOOO!

And it's been intermittently doing it all. day. long.

One thing is for certain. It is not a twitch. I googled "buzzing foot" and "vibrating foot". I might have a neurological disorder, specifically MS. I might have something wrong with my sciatica. I might have anxiety. I might need to poop. Seriously. That's what someone said. That advice is actually helpful as it allows me to take "neurological disorder" with a grain of salt. It could be...phantom. Great. That's all I need is to be making up phantom foot buzzing. As though I don't have quite enough going on in my life.

Honestly.

And now, not only is my foot vibrating which is just, well, high times, I also can't stop singing, "Foot, foot, foot, foot vibrations." It's an added bonus, really.

So, give me your best guess. Why, in the world, is my foot vibrating?
