That is my biggest fear! I remember, quite a few years ago, I was fixing something to do with the curtain rods, above my windows in the great room. I just used a chair, but made sure it was a stationery chair with no wheels. Everything went fine until I stepped down onto the floor. My dog's stainless steel bowl happened to be right where I stepped so my foot slid forward about 3 feet and I fell down, hard, on my back, hitting my head on the tile floor. I saw stars, and my head hurt like a *****! I probably should have gone to the doctor, but didn't.
I hate that when you fall, your brain doesn't seem to register what's happening until you are down on the ground.
Hope you don't have any complications. Do everything they tell you, and if something doesn't seem right, but they tell you that you should be fine, push to get more testing. Concussions are a very serious matter and with the ear problem and vertigo in addition, that makes it even more serious. 4951
