Is it ok to drink salt water to reduce painful period cramps and aches?

Sure: I don't know if it will help, but certainly you can try. If it's too salty you'll get dehydrated from it. Careful.

Never heard of that?: NSAID’s, SSRI’s, hormone meds, OTC meds containing diuretics, warm bath, heating pad, exercise & acupuncture are excellent for PMS / period. Avoid caffeine, chocolate, alcohol & salt. Get GYN eval to R/O underlying pathology. Consider omega- 3 fatty acids, magnesium (supplementation or through diet) or Black Cohosh with dr ok. Sipping Chamomile can dissipate pain. Ginger helps w nausea.
