Tips for helping with Lower back pain?

I have this dull lower back pain. I think it comes when I'm doing take offs with cheat 720s and cheat 900s. My friend does gymnastics and says he gets the same thing and he tells me to get a tennis ball and roll it on my back on the floor. I've been doing this but it only temporarily relieves the pain. Are the some other ways I can relieve it?

Edit: I guess my next best move is to just rest it out as well as do mild back and hip exercises. I guess I can take a break from tricking. Thank you for all the advice!
