I used to get these two or three times a year, but then I had heart surgery last summer and had five in the first day after I came round from the anesthetic, and two or three every day for weeks after that. They've now settled down to one every few days. Annoying, but they go away fairly quickly and just leave me feeling a bit tired and headachy for a few hours.

Same story for me, had a minor ablation procedure which triggered a bunch of migraines that later settled down.
