Complications

By Mayo Clinic staff

Spinal stenosis complications vary, depending on which nerves are compressed.

Cervical stenosis complications

  • Incontinence. In severe cases of cervical spinal stenosis, you may lose the ability to control your bowels or bladder.
  • Weakness or paralysis. Cervical spinal stenosis often causes severe weakness and sometimes paralysis.

Lumbar stenosis complications
Cauda equina syndrome is a rare but serious complication, in which the bundle of nerve roots at the lower end of the spinal cord is compressed. This can cause numbness and paralysis, and emergency surgery may be necessary to relieve the pressure.
