Help!

So I’ve been diagnosed with endo for 5 years now and for 4/5 years I was taking birth control continually to avoid periods. (This was recommended by my OBGYN) As of right now I’m off of birth control completely -resulting in the usual and terrible period symptoms. I’m currently experiencing excruciating lower back pain. It feels like I need to pop my lower back/hips but I know it could also just be cramping. Do you guys have any tips or tricks that help you with lower back pain?
