A brachial plexus nerve block is a procedure that alleviates chronic pain in the shoulder, arm, and hand by blocking pain signals from the brachial plexus nerves. It's particularly beneficial for nerve-related pain conditions like thoracic outlet syndrome (TOS), brachial plexopathy, nerve entrapment syndromes, and complex regional pain syndrome (CRPS), as well as persistent pain after upper limb injuries or surgeries.

The injection is administered at specific points along the brachial plexus, such as: - Interscalene (near the neck) – for shoulder and upper arm pain - Supraclavicular (above the collarbone) – for widespread arm pain - Infraclavicular (below the collarbone) – for mid-arm and elbow issues - Axillary (in the armpit) – for forearm, wrist, and hand pain

This nerve block reduces pain, inflammation, and muscle spasms, enhancing function and quality of life. For chronic pain, additional medications like steroids may be used to decrease inflammation or provide longer-lasting relief.

While generally safe, risks include temporary bruising, bleeding, or soreness at the injection site. Rare complications may include nerve irritation, infection, or pneumothorax (a collapsed lung), depending on the injection site. Ultrasound guidance is used to ensure accuracy and safety.

After the procedure, temporary numbness and weakness in the arm might occur but typically resolves within hours. Avoid strenuous activities until sensation returns. If pain relief is significant, this treatment can be repeated as part of a comprehensive pain management plan with physical therapy, medications, and lifestyle changes.

A brachial plexus nerve block may offer much-needed relief for individuals with chronic nerve-related pain in the upper limb. Consult your medical team to see if this treatment is right for you.
