26 years old, 5 foot 3 inches tall, 126 lbs, not sexually active, periods are irregular and usually quite far apart (month and a half to two months). When period does come, there are large clots, and extreme pain in the pelvic and vaginal region. Pain causes cold sweat, vomiting, and diarrhea. Pain is excrutiating and leaves me laying on the floor for hours, sharp pains coming 50 seconds on, about 10 seconds off, 50 seconds on,.. etc, etc. Hyperventalation causes pins and needles/vibrating sensation in the hands and sometimes face (mouth area) and feet. I've only ever been given naproxen for severe cramping although this sharp pain feels different, and naproxen seems to not help at all. Any ideas?
