Tbh, surgery was the best thing that happened . Not sure anything else would have fixed it in my case. I'm much stronger now than I was before popping my disc.
As I said in my first post, I'm not saying you have an issue with a disc. But that the symptoms you've had could indicate one, and as such to be sure before you return to training.
Whatever the issue is I hope you get it sorted soon, back pain really does suck. Disc based or not I'm sure you'll get back to full health
