I have this constant feeling of tiredness. I also feeling off balance but I am not. I went through an episode a few months ago where I woke up with double vision/off balance to the point of I felt I was walking to the right all the time. I could not hold myself up. It was awful feeling. Now I am always tired, I feel like my balance is off again but it is not, I also think I have loss of hearing from a few months ago. Any thoughts please.
