I had a lumbar laminectomy on my L4/L5 10 years ago. It was done as an outpatient surgery, and I was at home that night. First week was pretty rough, you need to learn how to walk, lay in bed, stand up from a sitting position, etc while causing minimal movement in your back. Second week was much easier. I seem to remember that I went back to work sometime during the 3rd week since I have a desk job.
Before the surgery, I had 9 months of extreme pain so bad I couldn't stand for more than 5 minutes at a time. I wasted most of that time with the "help" of a chiropractor who did nothing for me except take my money and prolong the pain by convincing me surgery was a terrible option.
On occasion, I still experience some pain, especially if I overdo heavy lifting. I still am able to jog/run and do high-impact sports, but my back always reminds me that it is not 100%. I would say that it is probably at 80-90%. I still have minor numnbess and occasionally very minor pain in my legs. I have gotten used to it and never notice it until I stop to think about it. Overall, getting surgery was a good decision and I would do it again. It changed my life from extreme pain to being active again.
My surgery was done by a neurosurgon. At that time, they seemed to be more advanced at performing a less-invasive surgery than many orthopedic surgeons. Also, keep in mind that this is not just a joint issue, but also a nerve issue. Since it's been 10 years since my surgery, I don't know if there currently much difference between the procedures performed by orthopedic and neurosurgeons. It may be worth a consultation with a neurosurgon as well to find out if they have different procedures or advantages.
