Yeah, all bruising from falling down the stairs.

My thumb was scraped up from the carpet when I fell, so I had like a huge hole in my thumb!!

What happened was, the double vision made me see multiple steps at once. I couldn't tell which step was real or not, so when I tried to step down on the stairs, I guess the step I wanted to put my foot on was just an artifact of the double vision (i.e., it didn't exist). I then tried grabbing for the handrail when I missed that step so that I wouldn't fall, but of course I saw "two" handrails instead of one. I apparently grabbed the one that didn't exist. lol. Then I fell down on my arm and thumb.
