Diagnosis

Bell's Palsy does not always result in paralysis. Other diagnosis would include pressure on facial nerve, infections such as Lyme disease, sarcoidosis, or facial wounds. Doctors will examine the patient and perform blood tests to check for Lyme disease. They will also do MRIs to check for brain tumors, or signs of a stroke. These tests are all ran to make sure it has nothing to do with these other conditions or problems, because the main cause of Bell's Palsy is unknown. If all of the tests come back negative then the patient has Bell's Palsy.
