Do you know if your spinal cord was injured/flattened and compressed before you had surgery? How long did you have symptoms before surgery and what symptoms did you have pre-surgery?

Have you had a recent MRI of your cervical and lumbar spine to see if you have new compression of your spinal cord/nerve roots? Have you gone to a neurologist for EMG/nerve conduction studies of upper and lower limbs?

My understanding is that with fusion, you are at risk for adjacent segment issues with vertebrae above and below the fusion section. With normal aging and continued degeneration, you may have new disc herniations and/or bone spurs. The alignment of your spine may have shifted.

Have you reviewed all of your MRI reports yourself or had a loved one help you look at everything? It may be good to see a new orthopedic spine specialist/surgeon for 2nd and 3rd opinions.

Are you being cared for by a pain management specialist and are you getting physical therapy?

If your spinal cord and nerve roots have been injured due to long term cord/nerve root compression/flattening, central/peripheral nervous system issues may worsen over time and cause miscommunication between brain and body/organs. This includes pain signals.
