I'm glad it was something simple. You never know when it comes to back pain. I have 2 joints in my lower back that pop out of place and when they do I wind up with severe back pain. I have to get on the floor on my back, pull my knees as close to my chest as I can (which would be easy if it weren't for my big belly) and the rock from side to side to pop them back in place and I could scream when it happens.
