Most patients are able to tolerate the procedure under local anesthesia alone, but some choose to receive IV sedation as well. Once you are comfortable, the physician will use a local anesthetic to numb the skin. Under x-ray guidance, the needle will be carefully guided towards the anatomical location where the ganglion of impar is typically located then a numbing anesthetic and/or steroidal medication will be injected. The procedure usually takes just 20 minutes or less. After a brief recovery period, you’ll be allowed to return home to rest.

Many patients report immediate relief following the procedure due to the anesthetic medication used during the injection. Occasionally patients may complain of soreness for 1-2 days following the procedure. Some patients may need a course of injections to obtain the desired level of pain relief.
