Speaking as someone who has been through the system many times.
Only people who have experienced back pain will sympathize with you, doctors will tell you "you may feel moderate pain" while never experiencing this for themselves. They push the steroid shots knowing its only temporary ($$$ for them), I'm sure you've seen it, they line you up like cattle and bang out 50 shots on patients in a row like an assembly line. They could care less if those shots work, they know even if it works its only temporary so you come back for another 2 or 3.
They will pass you off to the next doctor that will push the surgery next, which is never ideal because it will depend on the skill of the surgeon and if he doesn't make a mistake. And if he does make a mistake, he/she is in no way liable in anyway and will probably suggest another surgery knowing you have no recourse with the terrible pain you will have to deal with. And I know, that back pain will bring anyone to their knees. You're just a money bag of meat and bones to them. I was concerned about the risks and had a doctor literally tell me because he was annoyed with my questions, "it may fix it, it may make it worse, or you could die".
The problem is usually pinched nerves from a herniated disc, once the disc is herniated, it cannot be unherniated. Its going to constantly leak fluid causing compression of the nerves which in turn causes tremendous blinding pain. The lower back is one of the worst because they're big ass nerves that split down to your legs, so you may feel it going down your legs. The compression also causes inflammation which compounds the problem.
The best thing you can do is try to reduce the inflammation so that your body can heal somewhat, I found marijuana to be the best anti-inflammatory. Also have to excercise and try to strengthen the muscle tissue around the spine to help stabilize it so it doesn't get as compressed. Uphill grade walking and excercise bike are very good low impact excercises to help strengthen the back muscles.
There are also alternative treatments like stem cell therapy but these are crazy expensive.
You are still pretty young and in time hopefully you'll be able to heal or mediate most of the pain but the excercise will be a lifelong thing.
Just my personal experience, I hope it helps you. Best of luck to you.
