If workup for sacroiliitis is not illuminating, consider middle cluneal nerve entrapment. It is a known complication of lumbar surgery. I’m not sure if it is exacerbated by twisting

I had L3-L5 decompressed and fused with hardware in 2024. I need to be careful when maneuvering in bed or bending turning/twisting due to changes in biomechanics.

It can take a full year to fully heal from surgery. You may have pulled muscles, irritated nerves or have new compression. Have you done physical therapy?

If you don’t notice improvement over 2-3 weeks after applying ice, heat, rest, pain patches/creams (like lidocaine or Voltaren gel for inflammation), it would be good to see your orthopedic doctor again to get updated X-rays/MRI to see if anything shifted or if you have adjacent segment issues above/below your fusion.

Thank you for your feedback
