I have been getting migraines almost every time I do any type of cardio exercise, walking, treadmill, rowing, etc. 8 also get them riding in the car for long periods of time on a trip. A recent doctor visit suggests I may be getting motion sickness triggering a migraine. The headaches come in a few hours after exercising and while relaxing in the evening watching tv or reading. I feel great after exercise but then it starts later in the evening or for sure wake with one the next morning. Anyone else experience this or found a solution?
