ha, I had that done on Aug 2, 2016. Microdisc surgery partial, laminectomy
I am probably not a good person to ask as it did not help me.
Surely it has helped others.
And, the doc did say it can take up to a year for results.
No downsides. Except I have pretty bad back pain now. And even with "full insurance" the bills were breath-taking. And not a single person along the way, when asked, had any clue what I could expect to pay....although this is definitely another thread topic. Only bill left that I am aware of is $5,700.00 for a back brace made of nylon and velcro which, if it has more than $25 of material in it would shock me. The back brace helped a bit for 2 weeks after surgery but not thousands of $ worth. Good luck!
