Sometimes, during the course of surgery it is possible that nerves may become damaged. This damage can occur due to a nick from an errant scalpel, a bruise that occurs on the nerve, or because of inflammation of the tissue around the nerve. In many cases the nerve damage will go away over time, as the injured portion of the nerve heals or the inflammation goes away. In other cases, nerve damage from a surgery can be repaired surgically. However, sometimes the symptoms are permanent.

Nerve damage after surgery can also result in neuropathic pain, which is generally a severe burning pain.
Location of symptoms
These symptoms may occur far from the actual surgical site as the damaged nerve may supply distant parts of the body.
Exacerbation of symptoms
These symptoms may become worse due to sudden movements or unusual body positioning, such as those that occur during sleep.
Symptoms and pain medication
Pain that comes from post-surgical nerve damage will often not be alleviated by pain medication, even narcotics.
