Definitely stretch those hip flexors.
One thing I like to do when my back is acting up...I lie on the floor, hug my knees to my chest, and roll like an egg the entire length of my back, back and forth back and forth. There's something about it that just feels better.
Then I lie with my arms out to my side, pull my knees up and slowly lower them from side to side. If any of this hurts too much, don't do it.
Any tme my back hurts I just do as much gentle non-weight bearing manipulation I can do on the floor, and that seems to help. One thing that causes me back pain is sitting up in bed typing on my laptop, which I'm doing right now! So I have to tell myself to stop that.
Back pain is no laughing matter. Take it easy, but be active as much as possible.
