Sometimes, migraines just happen. There are quite a few people who get migraine headaches at some point in their life. Some migraines even cause nausea and tingling of your extremities. No matter what kind of migraine headache it is, I have found that, surprisingly, yoga helps.
We may not think that moving and stretching would help something that seems to be worsened by, well, moving and stretchy; but it does. Whenever I get a migraine headache, I try to lay down for a bit, take a bath or a shower to help it, then I finally accept the fact that doing some yoga could be great for me.
Ali K. created a great yoga sequence for headaches a few months ago. There is plenty of stretching and absolutely no strength building movement. Just what the doctor ordered. I would recommend doing this sequence after warming and relaxing the neck and back muscles. This can either be done with a heat pad, or by taking a nice, hot shower or bath. Taking some extra time in savasana tends to help as well!
