Pam,
You have been through so much. Can't help but wonder if the hernia work/repair?/mesh has anything to do with the gut pain.

Maybe the surgeon who did the abdominal hernias/mesh last week at the same time you were under having the spine surgery may be able to get some idea what might be going on in this area.

Even tho I had rectal cancer surgery in 2012; My abdominal pain problems were and are still much worse since the 3 abdominal hernias repair/mesh surgery in 2015. My spine pain from previous/fusion/laminectomy, as well as PN are no where nearly as painful as my abdominal pain .

Hope you don't mind my bringing this up; especially since your "gut" pain is much worse than the spinal fusion pain.
