I have 3 disc bulges, L5-S1, L5-L4, and L4-L3. I can tell you from my experience that using an inversion table, doing safe core exercises that do not put stress on your back, and anti-inflammatory meds help. Also, never bend over to pick up packages, bend at the knees, and use your hand cart a lot more. It's funny how one day you can feel like superman, having no idea that your back is on the verge of injury, until you make one wrong move, and that's it.
Also, I know a few guys that have had the epidural steroid injections, and they do help. However, I watched how they do it on YouTube, and that has kept me from trying it.
