I don't know about all the science shit, but since I ran 10 miles in 73 minutes on Thanksgiving, I shall quote that popular Marine Corps bumper sticker:
Pain is weakness leaving the body.
One can expect physical exertion that results in the growth of muscle tissue to be painful. Feel the burn. No pain, no gain.
...
Definitely read NGDawg's post later when your migraine subsides. A lot to be learned.
