An intercostal nerve block is a procedure used to relieve chest or rib pain by targeting the intercostal nerves, which run between the ribs. It can help manage pain from conditions like postherpetic neuralgia (pain after shingles), rib fractures, or discomfort after chest or abdominal surgery.

During the procedure, a numbing medication, with or without steroids, is injected under the rib to reduce pain and help identify the source of discomfort. X-ray or ultrasound imaging ensures accurate placement. The procedure is quick, and you’ll lie on a table while the area is cleaned and numbed before the injection. Afterward, you’ll be briefly monitored for any issues, such as shortness of breath.

Alternatives to an intercostal nerve block include pain medications, physical therapy, nerve ablation (such as radiofrequency treatment), or, in some cases, surgical options. The best approach depends on the cause of your pain and your response to previous treatments.

Before the procedure, avoid eating solid foods for eight hours if sedation is necessary and check with your provider team about stopping blood thinners since this is not always necessary. Most cases do not require sedation or pausing blood thinners, but this may depend on your provider. Arrange for someone to drive you home. Risks are rare but may include infection, bleeding, or, in very uncommon cases, a collapsed lung (pneumothorax). These risks are minimized with careful monitoring.

After the procedure, you may feel temporary soreness or numbness, but most people return to normal activities within a day. Track your symptoms over the next week and share them with your provider during a follow-up appointment to assess how well the injection is working.
