So today is the third day that I've done an hour on the elliptical (not consecutively), and after each time I got a pretty persistent headache afterwards. I've been trying to reduce the amount of pain reliever I use, but I find that is the only thing that relieves them (I usually can lie down for an hour or so and be okay).
I drink a lot of water while working out, so I don't think I'm dehydrated. I generally don't eat a lot beforehand (I find I get an upset stomach), but I like to eat something high in fiber/protein after working out.
Any tips on what might be causing it? I can always take pain reliever before I start working out to prevent it, but I'd like that to be my last resort if at all possible
