Getting microdiscectomy, any advice?

31M, 185 lbs. L5-S1 herniation

Have been dealing with sciatica off and on for 10 years but it’s never been constantly painful until 6 months ago. 2 shots didn’t do anything and I haven’t been able to get any relief with exercises.

Deciding to go with the surgery route at this point as it’s not something I can really live with. My doctor said as long as it works, there’s pretty much a 3% chance I would re-herniate in the future but I’ve also read otherwise.

Looking for long-term tips on how to keep everything in check, aside from the book, which I plan on getting. Mainly worried about the degeneration in my bottom 2 discs.

Thanks!
