Pain management for S3 endometriosis

I’ve been diagnosed with staged 3 endometriosis. I get extremely bad period pains which stop me doing daily tasks as I get horrendous abdominal and back cramps and really bad leg pain! I know the only way to help is getting surgery however as we are TTC my fertility specialist has advised to not touch the endo just yet. It would be helpful to know how some of you ladies manage your pain!! Painkillers, herbal teas etc any advice would be helpful ❤️
