Painful menstration

Patient: When i get my period. i am in so much physical pain that i could cry. I get really hot then im fine. I get really bad diarrhea. Its not just cramping but its also needle sharp pain throughout my whole vaginal and uterus area and isnt constant in the spot. Sometimes its just a jolt of pain and other times the pain stays and i cant move. My entire lower half hurts up to my kidneys and i feel sick.

Doctor:
