Probably.
Today I was telling a co-worker about how I slept so much this past weekend and I hope that doesn't mean I'm getting sick. She said maybe my body just needed lots of sleep. A little later she suggested maybe it's a concussion from when I hit my head really hard last week. I'd actually considered this, but said I didn't black out at all so that's not it. She told me I still could have gotten a mild concussion without losing consciousness at all. So I looked it up. And I think she's right.
When I say I hit my head really hard, I mean I hit it really, really, really hard. And it's so silly. I was bent over kind of in my washer Thursday night. When I stood up, I discovered (the hard way) that my dryer door apparently wasn't closed all the way. Rotten stackable washer and dryer. I crumpled to the floor in a heap and cried really hard. But I didn't black out.
According to the Mayo Clinic, most people don't lose consciousness when they get a concussion so they'd don't even realize they have one. Hmm.
On Friday it made sense that my head hurt really bad, but a concussion would certainly explain why I still have a bad headache, why my ears were ringing so much this weekend, and why I've been wanting to go to bed soo early. Good thing it's something that my body will fix itself! Our bodies are pretty nifty.
