Why is my head a barometer?

I'm sure there's a scientific explanation why my head feels like exploding every time the weather is foul. Even if  I knew what it was, I wouldn't care unless there was also a scientific way to stop it. I have considered drilling a hole in the middle of my forehead to release the pressure, but I'm thinking that would hurt and I'm opposed to more pain. I can take enough drugs to put a horse down and sometimes I can actually sleep instead of hurting. Or I can stay in a dark room with ice on my face and wait for the weather to change.

I love snow and rain! They're beautiful and magical. But they sure do hurt.
