I have been suffering from migraines for approx 10 years. I enjoy running however I think I may have to stop. I can workout in a gym and not get a migraine. However I can run a 5k to a marathon and end up with a migraine in the end. I don’t know why running does this. As much as I enjoy the run I am wiped out due to the migraine, not the run. Does this happen to anyone else?
