Well the straight dope is there are no nerve endings inside our heads and the vibrations or tingles we feel are in the surrounding muscle and bone tissue.

When we get headaches, we are feeling the same things in the outer and inner regions of our brain. That's why aspirin works so well, as it thins the blood enough allowing the thick blood building pressure easier passage through the brain.
