A lumbar epidural injection is a procedure to deliver medication into the epidural space in the lower spine. It is typically used to relieve pain in the lower back, legs, or sciatica. The injection contains a corticosteroid (to reduce inflammation) and a local anesthetic. It is usually performed under fluoroscopic (X-ray) guidance for accuracy. The patient lies face down or on their side during the procedure. A needle is carefully inserted into the epidural space in the lumbar spine. The medication is injected to reduce nerve irritation and swelling. Relief may begin within a few days and can last from weeks to months. It is considered a minimally invasive, outpatient procedure. Multiple injections may be needed, but frequency is usually limited. are epidural injections safe for lower back pain best injection for lower back pain does taking epidural have side effects epidural spinal injection price lumbar epidural injection near me
