Following the procedure, outpatients are monitored for 20 to 30 minutes and subsequently discharged home. Prior to leaving the department, all patients should be questioned about their symptoms to evaluate the likelihood of an immediate anesthetic response. Patients are instructed to expect that the anesthetic response will be transient and that they may experience a short-term, postprocedural pain flare-up for perhaps as long as a few days. If steroid was injected, the patient should be advised to monitor for a more delayed response typically occurring 3 days to 1 week after injection. A short-term prescription for a narcotic analgesic may be given to assist in managing a short-term, postprocedural pain flare-up.
Patients who respond well to an initial injection with subsequent recurrence of pain may potentially benefit from sequential injections, or possibly radiofrequency rhizotomy, as clinically appropriate. Care must be taken in repetition of steroid injections to avoid the potential side effects of cumulative steroid doses.
