My menstrual pain causes vomiting and fainting. is this normal and is there a way to stop this?

Talk with your doc: This is a quite severe reaction to menstrual pain and should be evaluated by a physician. It is not uncommon to have pain and cramping with menses, but fainting could indicate something more serious, such as anemia and you need to be seen by a physician.

You need med eval.: Reasons for significant menstrual cramps can be endometriosis, cervical stenosis, uterine fibroids, adenomyosis & pelvic inflammatory disease.
