Bell’s Palsy | Diagnosis & Tests


How does my doctor know whether I have Bell’s palsy?

There is no specific test to identify Bell’s palsy. Your doctor will probably ask questions about your symptoms and your medical history. Facial paralysis can also be caused by a stroke, a tumor or an injury, so your doctor will check to make sure that another condition is not causing your symptoms. You may need to have additional tests, such as an X-ray or a magnetic resonance imaging (MRI) test.
