I have been dealing with daily feelings of dizziness, light-headedness, blurred vision and difficulty focusing my eyes while driving for approx. 2-1/2 years now. Have had 2 MRIs of brain, 2 rounds of vestibular testing, X-ray of neck all of which came back normal. I have tried Chiropracter, allergist, massage therapy, and physical therapy which none have helped. I ve begun to believe that there is something wrong with my brain and eyes when it comes to interpreting what I am seeing. Any ideas of what could be causing the dizziness?
