I have 3 to 4 migraines per month. They last 72 hours each. I had an MRI a couple of years ago and didn't have a migraine for 7 weeks afterward. I know this may be simply a coincidence, but that is the only time in the last 41 years that I've gone more than a couple of weeks without a migraine. I'm curious if anyone else has had the same result from an MRI?
