Pounding, throbbing, stabbing, aching - welcome to the world of headaches, an ailment that affects more than 45 million Americanseach year. 

Humans have been suffering from the malady for millennia. Recorded depictions date back to at least 4000 B.C. in Mesopotamia, where it was thought that Tiu, the evil spirit of headaches, was to blame. The shenanigans ofevil spirits were assumed to be the cause of headaches throughout many cultures, and gave rise to trephination - a procedure in which a small circular portion of the skull was removed, creating egress for the pain-triggering spirits. 

Given how agonizing a headache can be, rowdy evil spirits wreaking havoc doesn't seem all that much of a stretch. Fortunately we know better now, and in most cultures no longer rely on holes drilled in the head for relief. But if not evil sprits, what does cause the pain?
