Good morning from a sunny South Arica.

My daughter (22) suffers from excruciating painful menstrual cramps every month. Her cycle is close to 28 days (give or take a day). She is getting married on 18 March and is still a virgin.

The pain (I realize that pain measurement is absolutely subjective) causes her to vomit. Scalding hot baths don't help any more. Pain killers (in SA we have Nurofen Period Pain esp for menstrual cramping) doesn't bring any relief. The only thing that somehow helps is 100% pure pinapple juice of fresh pineapples. She dreads her period every month.

She has PMS (well, then her siblings and parents suffer).
Her blood flow takes 3 - 4 days then taper off.

I had such painful periods myself as well as low blood pressure, causing me to faint on the first day. But it got better after my pregnancies (four full term and vaginal births) only to regress into the same pain ridden periods after the third child. Eventually, 2015 - 11 years later, I was diagnosed with Hshimoto's, started on the Autoimmune Protocol (an elimination diet based on the paleo lifestyle) and within two weeks had relief from symptoms And my painful periods were gone. Mild pain and discomfort are all that remain. My cycle is 23 days.

My daughter cut out gluten, sugar and dairy because of other symptoms, but it didn't help for her pains.

She uses tampons exclusively. Had an allergic reaction to pads (don't know if it is the filling or the outer part).

What can possibly cause her excruciating painful periods?
