What Worked for me, getting on my knees and elbows and kinda stretching out a bit hope you feel better

heating pad on LOW helped me a lot! bath for me wasn't comfortable because I couldn't sit in a decent position to relax the nerve, let alone get in and out...but a rice bag or heating pad is okay as long as it's only on your back and not near your belly

put tennis balls in a tube sock and lay on them. then you can move them as needed to the right spot
