I actually looked on this site specifically to look for a post about this! I think it's a kind of vertigo. I've been having it since this morning, though I was also a little dizzy last night. Now it's really bad. I thought all my physical symptoms were in the past and that I was on my way to recovering, but apparently not. Friday, I was bending over and I got an instantly terrible headache. I had that headache until today, but it's been replaced by this terrible spinning--feeling like you are falling upwards is a good way to put it! I also have ringing in my ears and this feeling of pressure in my face and behind my eyes. I'm just praying it goes away! I'm trying just to rest all day, so as not to aggrevate it. I am definitely not bending over again!
