Feels like someone stuck a large machete through my butt, vagina, uterus and pelvic region. why no permanent non-surgical cure to period pains yet?

There is help: For women who have severe pain with their menstrual cycle, some benefit from menstrual suppression.... Taking birth control pills in a continuous fashion so that you only have 4 periods a month. Something to consider? I'm sorry you're in pain. Ibuprofen can help, i see you are already taking that. Talk with your doctor, there may be some options!
