Spinal Canal Stenosis
A narrowing of the central spinal canal that directly squeezes the spinal cord in the neck or in the lower back — causing pain, weakness, and neurological symptoms that affect both sides of the body. The most serious form of spinal stenosis.
Symptoms
Mild to severe pain from the lower back through the buttocks, thigh, calf, and foot — both sides
Pain from the neck or upper back into the hands and fingers — one or both sides
Tingling, numbness, burning, or weakness in the legs, feet, hands, or fingers
Imbalance and gait disturbance — shuffling, unsteady walking, falls
Back or neck pain that comes and goes — varying with position and walking distance
Morning stiffness that may increase or ease with movement
Dizziness or vertigo with position change — cervical cord involvement
Reduced/trouble urinating or passing motion (bladder or bowel control) — a red flag requiring emergency assessment
Sudden or rapidly progressive loss of bladder or bowel control, bilateral leg weakness, or inability to walk are medical emergencies in spinal canal stenosis. Seek immediate care — delayed treatment risks permanent spinal cord or cauda equina damage.
