Look into the reverse hyper machine and give it a try. It's used to create traction and strengthen your back. It's best for slipped disks. The creator, Louis Simmons from westside barbell, invented it to avoid surgery.
My brother is going through this issue now. He did a McGyvered version of these in the gym for the first time yesterday and he says he can see it will help. I can't speak from experience but anyone I've heard that had back problems that's used it swears by it.
I'm thinking about buying one from rogue fitness for prevention.
Hope all y'all with back problems get relief.
