17134 Intercostal Nerve Block

Overview

An intercostal nerve block is a procedure that numbs the nerves running between your ribs. A doctor injects a numbing medication near these nerves to temporarily relieve pain in your chest or upper belly. It does not treat the cause of the pain, but it can help you breathe and move more comfortably while you recover or while other treatments take effect.

Intercostal nerve blocks are commonly used in hospitals and pain clinics, especially for people with rib injuries or ongoing chest wall pain.

Anyone with pain from rib fractures, chest wall injury, or certain chronic pain conditions may be offered this block. It is also sometimes used before chest surgery or procedures.

Symptoms

Common symptoms

• Sharp chest pain when you breathe, cough, or move
• Pain along one or more ribs
• Difficulty taking a deep breath because of pain
• Pain that limits movement of your arm or torso
• Aching or burning pain in the chest wall that may come and go

Symptoms in children

• Children may cry or guard their chest when moving
• They may refuse to move an arm or breathe deeply
• They may breathe shallowly or avoid coughing
• Young children may be irritable or less active than usual

Symptoms in older adults

• Older adults may have more severe pain from minor rib injuries
• Pain can lead to shallow breathing and increase the risk of chest infection
• They may need pain relief to stay mobile and avoid complications
• Multiple health conditions may affect treatment choices

Causes

Main causes

• Rib fractures from a fall, accident, or sports injury
• Chest wall trauma or surgery
• Chronic chest wall pain after surgery (such as post-thoracotomy pain)
• Shingles (herpes zoster) affecting the chest wall
• Nerve irritation after injury or surgery
• Certain chronic pain conditions affecting the chest wall

Risk factors

• Older age
• Osteoporosis (weak bones)
• Recent chest surgery
• History of shingles
• Conditions that cause chronic pain
• Participation in contact sports or activities with fall risk

When to see a doctor

See a doctor urgently if:

• You have severe trouble breathing or chest pain that feels like pressure
• You cough up blood
• You have a high fever with chest pain
• Pain is so severe you cannot move or breathe deeply
• You feel faint or dizzy with chest pain

Book a routine appointment if:

• Pain is not controlled by simple pain relief and affects your daily activities
• You have ongoing chest wall pain for more than a few days
• You are unsure whether the block is right for you
• You want to discuss pain management options

Diagnosis

A doctor will ask about your pain, examine your chest, and may review imaging such as an X-ray or CT scan. The decision to use an intercostal nerve block is based on your pain, your overall health, and whether other pain relief methods have helped.

Tests that may be done

• Physical examination
• X-ray of the chest
• CT scan if needed
• Ultrasound to guide the injection
• Blood tests to check for infection or other conditions

What to expect at your appointment

You may be asked to lie on your side or sit up. The doctor will clean the skin and use a small needle to inject numbing medication near the rib. You may feel a brief sting, then a warm or numb feeling. The procedure usually takes a few minutes. Your breathing and heart rate will be monitored.

Treatment

An intercostal nerve block is itself a treatment for pain. It can be used alone or alongside other pain relief methods, physical therapy, and treatment of the underlying cause.

Self-care at home

• Rest and avoid strenuous activity for a day or two
• Use ice or heat as advised by your doctor
• Practice gentle deep breathing if it is comfortable
• Take simple pain relief as recommended by your healthcare provider
• Keep the injection site clean and dry

Medical treatments

Doctors may use intercostal nerve blocks with other pain management approaches, such as oral pain relief, physical therapy, or repeated nerve blocks. In some cases, a thin tube (catheter) may be placed to give continuous numbing medication for a few days. Your healthcare team will tailor the approach to your needs.

Living with this condition

After the block, you may feel numb or weak in the chest area for a few hours. Avoid driving or operating machinery until the numbness wears off. You can usually go home the same day.

Lifestyle tips

• Gentle movement and breathing exercises can help prevent complications
• Avoid heavy lifting or twisting until your doctor says it is safe
• Follow your pain management plan
• Keep follow-up appointments
• Ask for help with daily tasks while you recover

Diet and exercise

Eat a balanced diet and stay hydrated. Gentle walking and breathing exercises are encouraged as comfort allows. Avoid strenuous exercise until cleared by your doctor.

Mental health and emotional wellbeing

Ongoing chest pain can be stressful and affect sleep and mood. The block may help you feel more comfortable, but if you feel anxious or low, talk to your healthcare provider. If you have thoughts of harming yourself, contact a crisis support service or your local emergency number right away.

Prevention

The need for an intercostal nerve block is often due to injury or surgery, which cannot always be prevented. However, you can reduce your risk of rib injuries by preventing falls, using safety measures, and treating osteoporosis if you have it.

Vaccines

Staying up to date with the shingles vaccine can reduce the risk of shingles, which can cause chest wall pain.

Screening programmes

If you have osteoporosis risk factors, talk to your doctor about bone health screening.

Complications

If left untreated

• Without pain relief, severe chest pain can make it hard to breathe deeply, which may lead to chest infections like pneumonia
• Chronic pain can affect sleep, mood, and daily activities
• Pain may slow your recovery from injury or surgery
• You may avoid moving, which can lead to stiffness and weakness

Long-term outlook

Most people get good short-term pain relief from an intercostal nerve block. The effect is temporary, but it can give you a window to breathe more comfortably and start moving again. Your healthcare team will work with you on a longer-term plan.
