Leg Bed Wedge
When I had a lot of lower back pain, my friend, who was a sports medicine major, told me to use this leg bed wedge. She told me that a lot of back pain comes from not having your body in a natural position while you sleep. This leg wedge is supposed to help keep the body straight. I'm not a trainer, so I don't know how it all works, but my back doesn't hurt anymore. Maybe it could help you too!
