Starting in the middle of the day yesterday, I began sporting a positively blinding headache. I beat it back with some Advil in the middle of the afternoon, but it was there waiting for me again when I woke up.
Getting whacked in the head with an axe would be an improvement.
Further, your brain isn't supposed to have pain receptors, so how come I can point to you on the stuffed Binky the Brain doll just where it hurts? It's my right middle frontal gyrus.
