Physicians limit the number of epidural steroid injections to a maximum of three to avoid systemic side effects of the steroids. Side effects are minimal and consist mainly of mild tenderness in the area of injection which disappears in 1-2 days. Success is dependant on the cause of the pain and how long the pain has existed. The sooner the treatment is instituted, the better are the chances of getting well. This treatment, along with analgesics and physical therapy has brought relief to thousands of patients, avoiding , in the majority of cases, the need for surgery.
