Overall, the procedure is very safe. As with any procedure, there are risks. The most common side effect is pain, which is temporary. Any time a needle is punctured through the skin, there is a chance of bleeding or infection that is very rare. Other rare side effects include spinal headache, nerve damage, worsening of pain, etc., which are extremely unlikely Who should not have these injections? If you are allergic to corticosteroids, specific local anesthetics, or ionic contrast, please notify your physician. Also, if you are taking any blood thinners (Coumadin, Plavix, Warfarin, Lovenox, Aspirin) please let your physician know ahead of time to help devise a safe plan for the injection.
The steroid medication begins to take effect in one to two days at which point you should start to see some benefit. The steroid effect continues to get stronger and stronger such that the peak effect occurs at about two weeks. Thereafter, the effect will stabilize and should last several weeks to months. Typically, the pain relief experienced from this procedure lasts 3-6 months, but there is significant variability from patient to patient and from one procedure to another. If and when the pain starts to return, this procedure can be repeated to try and attain some pain relief once again. Keep in mind that this injection may work very well for pain certain areas but may not help with others. This is normal. Areas of pain that do not respond may need other treatments, which you can discuss with your doctor.
