An axillary nerve block is a procedure to numb part of your arm for surgery without putting you to sleep, used for surgeries on the forearm, wrist, or hand. It can also manage chronic pain related to the axillary nerve.

This procedure is done under local anesthesia, meaning you are awake but the area is numbed. General anesthesia and monitored care are not usually needed, but mild sedation can be an option for anxious patients.

During the procedure, you’ll lie down with your arm stretched out. Using ultrasound, the provider guides a small needle near the axillary nerve in your armpit to inject medication that blocks sensation while avoiding blood vessels.

This option prevents pain during surgery without affecting breathing. The effects last 12 to 24 hours, so numbness may continue after surgery but will gradually wear off. You’ll be monitored to ensure this.

Beyond surgery, the axillary nerve can cause chronic pain if entrapped or irritated. This can occur after surgery, trauma, or strain. Injections with steroids or anesthetics may reduce inflammation and nerve pain. For long-term relief, they may be part of a broader pain management plan with physical therapy or medications.

There are some risks, like temporary bruising or soreness, but using ultrasound guidance helps ensure precision, reducing complication risks.

An axillary nerve block is a safe, effective option for surgical pain management and chronic nerve pain relief. If you have persistent arm or shoulder pain, ask your provider if this treatment could suit you.
