Killer Headache

For anyone who lives in the Midwest as I do you know what a blessing and a nightmare spring is. We buy tissue in bulk, drink copious amounts of liquid antihistamine and put cold compresses on our foreheads daily. Today is my turn apparently to feel like shit. It hurts to keep my eyes open, and since my job requires me having "eyes in the back of head" along with the red, itchy ones up front, I am suffering. Any suggestions for headache relief? Ive tried caffeine, over the counter meds, and an ice pack - nothings touching this one. Please leave a comment with your brilliant ways to relieve the hammering in my head!!!
