I get awful pain in my thoracic spine and right under my ribs as well as painful bloating and nausea hours before I get my period and I haven’t found anything that helps the pain subside, I can’t sleep or eat and I’m just completely miserable for an entire day before I finally start my period. This doesn’t happen every month sometimes it’s every other month or every 3-6 months but I never know when it’s going to happen. I’ve tried stretching my back, taking baths, heating pads, tens unit, acetaminophen, muscle relaxers, and NOTHING helps!! I have gotten a vaginal ultrasound to check for cysts and they found that everything is normal and healthy. Do you have any idea what it might be?
