period pain
"I have always had severe period cramps, fainting, nausea, and stabbing pains. Naproxen 500 has been the only (non birth control remedy) that greatly relieves my pain. It's tricky because you have to get the timing just right, not too soon before period cramps start or too late after they already started. You must start it the moment you feel cramps. Starting before your period isn't as effective because that's not how this medication works best."
