I have endometriosis, so I have permanent pelvic pain from it. My periods were severely painful, and super debilitating so I'm not allowed to have them anymore. My best suggestions are a constant flow of naproxen and acetaminophen mix, heating pads, a TENS unit [if you can afford one- they're super useful], and biofreeze / tiger balm / lidocane [numbing topical gels / creams]. That's what I can think of off the top of my head. I'm on a ton of treatment for my pain ranging from drugs to physio to acupuncture to yoga and meditation.
