I have what I thought my be vertigo (as I've had it 6 yrs. ago). It's been a week today and still feeling off balance and swaying a bit when I walk. When this started a week ago, room was spinning but not so much the spins anymore but feel like things are moving when they're not and if I put my head back I feel like I'm on a roller coaster. Other symptoms, sleeping 10-13 hrs. at a time and occasional stomach ache on and off. Today I feel very sluggish and exhausted.. My appetite is good. I'm someone who works out but not feeling energetic enough to do so these days. Any thoughts.
