Neuropathy – axillary nerve
Definition of Axillary nerve dysfunction
Axillary nerve dysfunction is a loss of movement or sensation of the shoulder because of nerve damage.
Causes, incidence, and risk factors
Axillary nerve dysfunction is a form of peripheral neuropathy. It occurs when there is damage to the axillary nerve, which supplies the deltoid muscles of the shoulder. A problem with just one nerve group, such as the axillary nerve, is called mononeuropathy.
Signs and tests
Your health care provider will examine the arm and shoulder. There may be weakness of the shoulder with difficulty moving the arm.
Some people do not need treatment, and they get better on their own but the rate of recovery is variable and can take many months.
It may be possible to make a full recovery if the cause of the axillary nerve dysfunction can be identified and successfully treated.
