I have recently had some loss of balance issues. It can happen when sitting or standing and I haven't noticed any pattern. It feels like the earth moves down and to the right. Yesterday I was standing and I fell over to the right. Again, it felt like the earth moved. Immediately afterward I felt a little nauseous and needed to lay down for a few minutes, but then I was fine. Other symptoms I've had which may or may not be relevant include insomnia and frequent urination. I'm sure I should see a doctor, unfortunately, I don't have insurance and can't afford a doctor's visit - let alone the tests they may want to run. Any clues from anyone with this kind of experience?
