What to expect from a cortisone injection for piriformis syndrome

The clinician reviews the location of your pain and may use imaging to guide the needle toward the piriformis region. The skin is cleaned first, and local anaesthetic may create brief stinging, pressure, or temporary numbness. Corticosteroid is intended to calm inflammation near the muscle and surrounding tissues. It does not automatically correct muscle tightness, movement patterns, or a problem arising elsewhere in the lower back or pelvis. Improvement can be gradual, incomplete, or short-lived, so the response is considered together with the examination and your function.

Tell the clinician about blood-thinning medicine, diabetes, allergies, infection, pregnancy, or a previous reaction to injections. Ask whether someone should accompany you if numbness affects walking or driving. Afterward, follow instructions about sitting, walking, stretching, and exercise. Avoid heavy or repetitive activity until advised, then return to movement gradually. A planned rehabilitation programme may address hip strength, flexibility, posture, and load management once the area is comfortable. Keep track of changes in pain, tingling, walking, and sleep.

Call the treating service for increasing redness, warmth, swelling, drainage, fever, or severe injection-site pain. Seek urgent help for breathing difficulty, facial swelling, fainting, or a rapidly worsening allergic reaction. New or worsening leg weakness, loss of bladder or bowel control, or numbness in the saddle area requires urgent assessment.

Ask how the target was identified, what symptoms the injection is expected to affect, when rehabilitation can begin, and what other causes will be considered if leg symptoms persist.
