Drink lots of water and Gatorade/Powerade. I had one of those headaches on Saturday because I was outside all day working (national guard training
) and didn't drink enough water, they almost gave me an IV because I was about to have a heat stroke or something. ANYWAY, you might be a little dehydrated, and that causes killer headaches, kinda like a hangover.
If it doesn't go away, see the doc. But I am sure it is nothing! Get well soon!!
