I don't know how many days out you are post op, however, I had this surgery, plus discectomy, cage/spacer placement, and quite a lot of cleaning out bone spurts, so my spinal nerves could be freed up prior to the cages/spacers/disk replacements could be placed. I also experienced sciatic like pain post op. I say sciatic like, because it resolved, within 14 days, and has never again returned. That surgery was 3 years ago. I have had many. I have a congenital syndrome which causes a ton of orthopedic issues plus advanced osteo arthritis and rheumatoid. Fortunately, or unfortunately, depending on your take, the pain will pass, if you continue to try to move as much as possible, by walking, be that around your room, down and up a hallway, or wherever it works and provides additional distractions. 5 steps down and back, is better than 0 steps. Then after a while, 6 or 7 steps down and back, changing the numbers as you see fit. Add ice to the pain control, you'll be pleasantly surprised! I promise. I do better with ice than any ingested medication. 20 surgeries and counting. Push yourself, but get behind the pain control first. Toss some ice packs on the area, get in a rest, and then try. Slow and steady wins the race. There will be pain. Surgery will result in pain post, and pain meds will not reduce that to zero while healing. It is the inflammation that causes the pain, which is organically how the body heals. Be patient with yourself in accepting that. Keep trying. The ice will help a ton if you just tell the brain to shush up a minute, and try some. Honest.
