Ever since my fall last week (actually, it’ll be two weeks on Thursday), I’ve been having these weird dizzy spells whenever I lie down, recline, change positions when lying down, or just look up. Turns out I have something called BPPV (Benign Paroxysmal Positional Vertigo):
Typically, symptoms occur upon lying down, turning the head to the right or left, arising from bed, leaning forward, and looking upward. The problem appears to be loose particles that float in the inner ear, stimulating the dizziness. These attacks are usually of 30-90 seconds in duration and occur with positional body changes.
It’s caused by loose particles in the inner ear, is essentially harmless (although it’d be awful if it happened while driving!), and often occurs after a head injury. It’ll go away eventually. At least now I know. 
Sorry to hear about the ongoing side effects.
A friend of mine had something similar as a result of a virus that somehow causes those loose ear particles. Her neurologist put her on something like an amusement park ride that spun her around till they got back in place. What was most interesting to me was that they could tell when it had worked, by looking at her eyes.
I hope your loose particles relodge themselves, naturally and quickly.
How is school going?
Yep, the definitive diagnosis is made by some sort of “jumping” thing that your eyes do when the head is held at a particular angle, usually while reclining. Weird, huh?
School’s going well, although I’m sort of overwhelmed with homework right now as the Quarter is winding down. Only about a month more of Spring Quarter. This has gone really fast! I’m hoping to post a bit of a school update later this week. Thanks for asking, Dana!

Yikes! Praying for you and your recovery!!!
That is called Nystagmus. Children in the autism spectrum often lack it so they can go on the wildest rides without getting sick. They diagnose it by spinning a child and seeing how the eyes respond.
