Last Sunday I was running around the lake and slipped on ice - landed on the back of my head. I was taken to the hospital and they kept me for 30 hours. They did a ct scan and said no skull fracture, but I had the equivalent of a basebal on the back of my head and they said that I had the same amount of swelling on the inside. So a concussion and something about a hemotoma (sp?) Anyway, I can't really hear out of my left ear and I can't smell/taste anything. I think that I can tell sour, but not so sure about sweet. I am wondering how temporary this could be due to swelling? The Neurologist looked at me and said I need to see him in a week. I'm a little nervous about this and just wanted to know the general odds or percentages when you have a concussion and your smell/taste and hearing come back. Thank you.
