I had trouble with bumpy roads, and driving the lawnmower and tractor. My pt gave me exercises that helped with that. I had to be careful when and how much I did because if I overdid it I would get a migraine. He had me put my hand on the side of my head and push against it left and right through the full range of motion, there were others for my upper back and the back of my neck and at the same time I did tons of gentle stretching and work on my posture. It helped a lot, but I was very diligent. After a few weeks I could mow the lawn without getting sick. I still do the exercises after 3 years because I find it helps keep the migraines away.
