I'll run in the morning, feel fine all day, and then out of nowhere get a headache about 9:00 pm. It happened several times in a row before I figured out the pattern. Mostly, they haven't been that bad.
Saturday evening though, after my rough 20 miler that morning, I got a headache that hit me hard. I took Tynenol PM and it knocked me out, but my head was still throbbing all day Sunday and even Monday morning.
I asked my good friend, Google, and he said I might not be hydrating enough. I drink a lot while I'm running but I guess I'm probably not drinking enough afterwards. (I'm definitely eating enough- so don't worry about that.)
What do y'all think? Have you ever had this problem?
