Axillary Nerve Injury

What is Axillary Nerve Injury or Axillary Neuropathy?

The axillary nerve can be injured due to a direct trauma to the outer arm or after a shoulder dislocation or due to nerve compression. Blunt trauma to the shoulder can also cause traction injury to the axillary nerve. Usually treatment is not required, the nerve heals on its own and the symptoms start abating. Anti-inflammatories can be given for pain and swelling relief. PT can also be done. If symptoms persist, surgery is required.
