Injection of medications into nerve bundles, joints and spinal spaces is the basis of interventional pain management. By precisely injecting any of a variety of medications or substances, physicians can treat and diagnose a wide variety of chronic pain conditions. These minimally invasive procedures are used to treat chronic spinal pain, malignancies, nerve damage and numerous other related pain disorders. Pain management injections provide an alternative treatment for patients who have tried other treatment options with little or no success.
