I am curious if motion sickness and migraines have any neurological links. I've been a bit insecure in my balance my entire life and prone to motion sickness. As a child the motion sickness affected me less and got worse as a teen on wards (which is also when I started to get a lot of my migraine symptoms full strength). Being in a vehicle in particular makes me extremely ill, motion from a movie (especially 3D ones), seeing things move too quickly, moving my head too fast, anything which either is moving visually or physically moving me. I can also feel dizzy or off balance from a migraine in itself, and the motion triggered dizziness often causes a migraine. The thing which confuses me is when I was on topamax for a year (the only medication so far which worked for my symptoms) my motion sickness was dramatically reduced by it. I was able to do many things including rock climbing, international travel, long drives, etc without getting ill. Now that I am off topamax, just an hour in a vehicle made me throw up 6 times and I am still recovering from it.
