I m having episodes of debilitating motion sickness, headache and light sensitivity that comes and goes. I had my worst episode last summer with all of the above plus balance issues. I had an MRI at that time because the neurologist wanted to rule out a stroke and it was negative and so it was marked up to a virus that effected my labyrinth. I m 58 years old in good health with only celiac. Could this be a form of migraine? What else could it be?
