I have a very effective method: soak a cup of hot milk, put two spoonfuls of honey in it, and then drink it while it is hot. After a while, my stomach will not hurt. The students in our dormitory have stomachache during menstruation, so I always let them do it. Some took care of it once, and some never hurt again. Try it, too. I wish you an early escape from the "sea of misery"!
