Sharp pain above right eyebrow

For the last six years (roughly) I have randomly gotten a sharp, stabbing pain above my right eyebrow. It comes at random times but always begins around 3 pm. Migraine/headache medications do not work, neither do sinus pills. The only way to get rid of the migraine is to go to sleep for the night.

Is there a specific reason I get these migraines? Should I consult a doctor?

I get that too. I'm have never gotten an answer for why. And stress and tension seem to take the blame for everything. But I think it just could be where an effected nerve lives and just gets some people.
Personally I would be the first volunteer to wear a bio suit and be hooked up to stuff and go about my day if only they could research the workings of migrane / fibro/ RA to find out why this happens to us !
