Hello dear I understand your concern Very painful menstrual cramp could be due to primary/spasmodic type, secondary causes like pelvic inflammatory disorder, vaginal infection, endometriosis. I would suggest to consult gynecologist and undergo examination, reproductive hormone analysis, USG scan, blood sugar , urine tests, CBC to rule out cause. Specific treatment depend on cause Birth control pill will help you to decrease pain Drink plenty of water/juice Take healthy diet with lots of fresh fruits and green leafy vegetables in small frequent meal Avoid: high salt/fatty/oily food, alcohol, smoking, tea, coffee in second half of period Take physiotherapist advise to increase pain threshold Do regular exercise like walking, running followed by medication to combat stress, maintain proper pelvic hygiene If pain is not tolerablet then you can take tablet meftals spas for 2-3 days Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
