Diagnosing Neuritis

In order to diagnose neuritis, your doctor will perform a neurological examination in addition to a physical examination to pinpoint the location of the pain and to determine the nerve that is causing your pain. During the exam, your doctor will ask questions such as where your pain is located and how long you have been experiencing the pain. Be sure to share any medical information with your doctor, such as pre-existing conditions and any medications you may be taking.

If necessary, your doctor may request additional tests such as a blood test or a test of your muscle strength. An MRI, nerve biopsy, skin biopsy, electromyography (EMG), or nerve conduction velocity (NCV) tests may be needed. Your doctor will discuss the test and the reasoning behind the test with you in detail at your appointment.

 

Treatment of Neuritis

The first step in neuritis treatment is to address any contributing or underlying conditions, such as autoimmune disorders of infections. Many times, once the underlying condition is resolved, the neuritis will resolve on its own. Your doctor may recommend lifestyle changes, such as eliminating alcohol use and exercising to help reduce symptoms. If medication is necessary for pain, your doctor will discuss options with you. In certain situations, surgery may be recommended.
