Has anyone had laminectomy then needed spinal fusion?

I had multilevel laminectomy (l2-l4) in October 2024. I had severe nerve spasms before final postop visit. I was told my nerves were "waking up". I felt like the surgeon was dismissing my pain. I am now scheduled for a spinal fusion with another surgeon. I am afraid to be hopeful based on the laminectomy results.
