Bell’s Palsy
Description
Bell’s palsy is a temporary paralysis or weakness of one side of the face due to inflammation of the facial nerve. The exact cause is unknown, but viral infections (such as herpes simplex) may trigger it. Symptoms include drooping of the mouth, inability to close the eye, loss of taste, facial pain, and drooling. It can resemble a stroke, but unlike a stroke, Bell’s palsy does not affect other body parts. Treatment includes corticosteroids, antiviral medications (in some cases), eye protection, and physical therapy. Most people recover within weeks to months, though some may have lingering effects.
