Symptoms of Bell's Palsy
Return to Home Page  Return to Symptoms Page

Bells palsy occurs with swelling of the facial nerve (Cranial Nerve VII) as it passes through the skull. People usually develop drooping of the mouth and weakness of the eye muscles on the same side of the face impairing the ability to close that eye.

Other Bells palsy symptoms may sometime include impairment of taste, pain in the ear, or increased sensitivity to sound on the effected side.


The cause of Bells palsy is not entirely understood. The facial nerve swelling is thought to be idiopathic. There might be a viral component to this disorder.


Herpes simplex has been implicated. People diagnosed with Bell’s Palsy often have a history of a recent viral illness.
