Third trimester back pain

Brittani

I am currently 33 weeks pregnant with my third child (first boy) and the back pain is absolutely unbearable. I have taken Tylenol, Ibprofuen, and Aleve and nothing is helping. I’ve tried the heating pad and ice packs and still nothing. I do have back issues due to a wreck as well but my other pregnancy’s I never had the pain like this that makes it absolutely unbearable to move day to day. Has anyone been prescribed anything to help and if so what?
