I have had dizzy spells for 11 years now. Have had all kinds of test and nothing comes up. Had surgury on one ear also and nothing helped. Has ANYONE had this kind of problem. I am about to give up trying to find out what is wrong. By the way Mayo Clinic turned me down. They told me to save my money and time, that everything that could be done was being done. Marilyn, a Mayo Clinic turn down.
