Intercostal Nerve Block
Injections are under the targeted rib, and help relieve pain in the chest caused by shingles or a post-surgical chest scar.
During the Procedure
This procedure only takes a few minutes. The injected steroid reduces any inflammation and swelling of tissue around the intercostal nerve.
Discomfort during the procedure should be minimal since the injection site is numbed with a local anesthetic using a very thin needle during the performance of the block. Afterward, the patient rests briefly in the office. Most people can drive themselves home, but should take it easy and not return to work or other taxing activities until the next day.
If a patient desires further sedation, that is certainly available. Usually this isn’t necessary and sedation does increase recovery time. Also a patient must then be driven home.
Patients are advised to be aware that after the injection, pain may seem to be gone; this is due to the anesthetic and will only last for a few hours. Unfortunately, the original pain will likely return in addition to some soreness at the injection site. The good news is that in three to five days, longer-term pain relief is possible.
Degrees of response vary. For a patient who some or much improvement, additional injections may be worthwhile.
