About two weeks ago I tipped over backwards in my chair trying to jump over a door threshold. I tried to get my arm behind my head to cushion the fall but was a little late hence my melon made contact with the cement driveway. Long story short about four days ago when I sat up in bed to get dressed the entire room started to spin around just like in my old drinking days. Doing a google search I came up with this possible cause. Benign Paroxysmal Positional Vertigo. According to the information from my goggle search it seems that this is caused by some type of crystals breaking free in my inner ear. There seems to be a couple of possible fixes for this. However one requires another person and one is a self help type. I was wondering if anyone has done the self help method and if so did you have any luck with it.
