It's great to read about issues women face that are rarely talked about. As someone who has dealt with severe cramps, I have found a few things that helped in addition to the ones you mentioned. Cutting gluten, dairy, sugar and processed food from my diet significantly reduced my pain levels as it cut down on the inflammation in my body. Using a mix of saffron, garlic, black pepper and ginger brewed in a tea also helped curb the pain. Understanding the hormonal cycle and how it relates to your menstrual cycle and adjusting your exercise and eating based on each phase can also assist. Hope this helped.
