After my 2nd surgery I was pretty much totally deaf. At that point if someone called me on the phone I could hear them perfectly in my right / good ear, I'm completly deaf in my left ear. Two weeks later I went to get my staples out on both sides, with no improvement in my hearing. My Dr. said my right ear was filled with fluid and that it would clear up on it's own, come back in a month. I went back in a month and stll could not hear, it still had fluid in it. He extracted it, having a needle stuck thru your ear drum is very painful, but I had instant hearing in my right ear. On about 3 or 4 occasions since then my right side hearing has gone down a little but bounces back within 24 hours, I guess it is just fluid. If you had good hearing in both ears and one gets some fluid in it I guess you wouldn't even notice. On those 3 or 4 times it happened my own voice sounded differently and other sounds were different............very scary. Once in a while if I yawn or swallow my hearing improves just a tad, it is probaly the eustachian tube opening to drain the fluid. I can function very good considering being deaf in one ear and the balance issues............if I ever needed SSD it will because I'm totally deaf, I've experienced that for a about a month.......no fun at all.
Oh, one thing I did get out of all of this is handicap seats in the first row for all the Baltimore Ravens games..........
