My oldest brother suffers from migraines. Most of my headaches are tension related, however, sometimes I get headaches which aren't due to tension. I've been told they're migraines, but they certainly don't hit me like they do my brother. They've never been bad enough, or frequent enough, to warrant a trip to the doctor for any kind of official diagnosis.
When I get them, the ONLY way I can get rid of them is to eat something, take some Motrin or Tylenol, then take a nap for a while. In a darkened room. If I don't do this, they absolutely will NOT go away.
I don't get them often...but I long ago figured out one thing that will trigger them: red wine and wine coolers (the wine coolers don't have to be red). Even a partial glass will bring it on...and if I drink more, it gets much more worse. So I stay away from those. I think it's the nitrates in them, but I can't confirm it. And I don't seem to get any headaches from other food sources that may have nitrates in them. Whatever...I still stay away from them.

(checks forum I'm posting in) anal orifice on fire could be used for pain treatment would actually work as a pain killer, but it's very much true. Topical (and even other applications) work for a wide variety of pain issues. I've never tried it myself, as my own methods described above seem to deal with my headaches whenever I get them.
