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.
Corticosteroid side effects may cause weight gain, water retention, flushing (hot flashes), mood swings or insomnia, and elevated blood sugar levels in people with diabetes. Any numbness or mild muscle weakness usually resolves within 8 hours in the affected arm or leg (similar to the facial numbness experienced after dental work). Patients who are being treated for chronic conditions (., heart disease, diabetes, rheumatoid arthritis) or those who cannot temporarily discontinue anti-clotting medications should consult their personal physician for a risk assessment.
