I'm sorry - I know just how miserable migraines are.
I have chronic daily migraines so my experience is a bit different from yours. But yes, I've had an intense workout trigger a migraine. I've also had showering with hot water or blowdrying my hair trigger them.
When I first began working out, I'd get an exercise-induced migraine pretty much every time. I got clearance from my doctor to keep working out and advice on how to handle the migraines. She said that her migraine patients who walk daily do far better than her sedentary patients.
Anyway, I'd say let your doctor know. New types of migraines should be checked out just to be safe. It's also a good idea to write down on a calendar or journal the dates you have migraines and the circumstances surrounding them. That information can help reveal if there is a pattern.
