What to expect from an epidural steroid injection for spinal stenosis

Spinal stenosis narrows the space available for nerves. In the lower back, this can cause back or leg symptoms that change with standing and walking. An epidural steroid injection places anti-inflammatory medicine near the affected nerves. It may reduce irritation for a time, but it does not reverse the narrowing or remove bone and tissue.

Your clinician considers your walking pattern, pain, numbness, strength, scan findings, medicines, allergies, infection history, and bleeding risk. After the skin is numbed, imaging guides the needle. Pressure or brief discomfort may occur, followed by a period of observation.

Tell the clinic about blood-thinning medicines, diabetes, pregnancy, allergies, and recent illness. Follow instructions about eating and medicines, and arrange transport if sedation is planned. Once home, follow the advice on dressings and bathing. Gentle walking may be encouraged, while heavy lifting and strenuous exercise should wait for clearance.

Record how far you can walk, whether you need to sit or lean forward, and how pain, tingling, or numbness changes. These details help distinguish symptom relief from a temporary change and shape decisions about physiotherapy, exercises, or other care.

Contact the clinic for fever, increasing redness or drainage, severe persistent pain, or concerning symptoms at the injection site. Seek emergency care for new weakness, loss of bladder or bowel control, numbness around the groin, severe headache, trouble breathing, fainting, or an allergic reaction.

Ask whether your symptoms match nerve irritation from stenosis, what the injection can and cannot change, how medicines should be managed, which walking or exercise limits apply, and what options follow if function does not improve.
