What to do against headache?

This is so true it hurts. Take BC power or wear a foam neckbrace. I had really bad headaches and my doctor said it was from my neck muscles. Wearing the neckbrace for about 20 minutes does wonders.

or a too high bun

Ironically, I have a brain tumor and my constant headaches went away. Before the tumor I had super bad headaches. It's benign, BTW. I just fall down a lot and sometimes have trouble making complete sentences.
