I never used to get motion sickness and now I get it all the time. I had the flu back in March and ever since that I feel spacey a lot. I was treated for ear infections, a sinus infection, and allergies. Nothing seems to help. What else could it be? I had a CBC done and all came back perfect. My thyroid, electrolyte levels, and eyes have been checked and everything good. 30 yr old female. Very active, not overweight, exercises regularly.
