Axillary nerve dysfunction is nerve damage that can lead to a loss of movement or sensation in the shoulder.
Neuropathy - axillary nerve
Axillary nerve dysfunction is a form of peripheral neuropathy. It occurs when there is damage to the axillary nerve. This is the nerve that helps control the deltoid muscles of the shoulder and the skin around it. A problem with just one nerve, such as the axillary nerve, is called mononeuropathy.
The usual causes are:
Entrapment creates pressure on the nerve where it passes through a narrow structure.
The damage can destroy the myelin sheath that covers the nerve or part of the nerve cell (the axon). Damage of either type reduces or prevents the movement of signals through the nerve.
Conditions that can lead to axillary nerve dysfunction include:
In some cases, no cause can be found.
Symptoms may include any of the following:
Depending on the cause of the nerve disorder, some people do not need treatment. The problem may get better on its own. The rate of recovery is different for everyone. It can take many months to recover.
Anti-inflammatory medicines may be given if you have any of the following:
These medicines reduce swelling and pressure on the nerve. They may be injected directly into the area or taken by mouth.
Other medicines include:
If your symptoms continue or get worse, you may need surgery. If a trapped nerve is causing your symptoms, surgery to release the nerve may help you feel better.
Physical therapy can help maintain muscle strength. Job changes, muscle retraining, or other forms of therapy may be recommended.
