I was a candidate back around 2000. Same spot with a herniated disc. I had a consultation with the neurosurgeon to look at my MRI and he asked if I had seen any improvement at all since the injury and I had seen a bit so he suggested we give it another 12 weeks. After those 3 months I saw more improvement and decided to wait some more. I never did reschedule with the doc and it took a few years and you never fully graduate from the school of sore backs, but I eventually got back to 90% without surgery. At this point I'm glad I didn't go under the knife.
I went through that for a couple years.
I swear every time I'd start to consider surgery, I'd start to improve
a little. So, I'd decide to wait and then inevitably it would get really bad again. This roller coaster continued until finally I decided I didn't have much to lose. My
overall quality of life was quite low, and the odds of success with a microdiscectomy are quite good.
I scheduled the surgery and sure enough, started to feel a bit better. But this time I was committed -- basically a "fool me once, shame on you. Fool me dozens of times over years, shame on me."
But I am agreeing with @ripcord -- if you go to a
surgeon with a herniated disc, all a
surgeon can do is cut on you. If this is a recent injury, you may wish to give it time. The body's ability to heal can be remarkable.
Each individual must decide when they've lost too much time and want to try more drastic measures. There's no one answer or formula.
Also, an honest surgeon will give you honest odds on reduction in back pain, reduction is sciatica, and more. You'll likely find that if those were Vegas odds most people would be millionaires.
The last observation I'll mention: quite often we speak of pain on a scale of 1-10. What few understand -- and we quickly forget -- is that an occasionally brief 10 with periods of zero to 2 in between is WAY better than a constant 5 or 6. After months and years of
nonstop 5, 6, 7 and more, you're emotionally raw. It was hard on my marriage and every aspect of my life. Be prudent but set a timeline for how much life you're willing to lose to pain, and weigh this against the odds of an improvement with surgery.
