Does Epidural Steroid Injection Treat Spinal Stenosis?

Spinal stenosis is a reduction in the space available for the spinal cord or nerves. An injection places corticosteroid and a local anaesthetic near irritated nerves. This can calm inflammation and make walking, sleep, or rehabilitation easier when nerve pain is part of the problem. Relief varies and may be temporary; the injection cannot remove bone, disc material, or other tissue causing the tight space.

A clinician should match the injection approach to your symptoms, examination, and scan findings. Ask what pain it is intended to target, how long improvement might be assessed, and what other options support mobility. Gentle activity, prescribed physiotherapy, and changes that reduce painful positions may be used alongside it. Follow preparation and aftercare instructions, including when to report worsening symptoms.

Seek urgent medical care for new loss of bladder or bowel control, numbness around the inner thighs or genitals, rapidly worsening leg weakness, or severe symptoms after an injection such as fever, spreading redness, or a severe headache. Arrange review when pain, walking ability, or weakness is steadily worsening.

Which symptom is the injection expected to improve? What are the alternatives if relief is limited? Could my weakness or walking difficulty need a different assessment?
