Bell’s palsy is one of the more common forms of facial paralysis. The exact cause is unknown, but it is suspected that a virus causes inflammation of the facial nerve. In most cases, symptoms will clear up over the course of six months; some people, however, will have recurring episodes or more chronic symptoms.
Symptoms Overview
The symptoms of Bell’s palsy have a rapid onset. Although most cases resolve themselves without assistance, it’s still wise to go to the doctor to rule out other facial paralysis issues. Lyme disease, tumors, stroke, and other disorders can cause facial paralysis as well—and these are much more serious diseases. The nerve attached to the facial muscles, which passes through a little bone passageway, not only controls muscles in the face, but also the eyes’ ability for tearing, the production of saliva, the ability to taste. Hearing may be more sensitive when the nerve is inflamed as well.
The visible aspects of Bell’s Palsy include a drooping of the corner of the mouth and the eye on the same side failing to close as normal. The lower lid may droop as well. This can make it difficult to form any facial expressions. Additionally, the eye may tear up more or less than normal. Some patients suffering from Bell’s palsy find the amount of saliva in their mouth changes as well, causing drooling or excessive dryness.
Other symptoms of Bell’s palsy include difficulty tasting things, headaches, and jaw pain. Additionally, there may be an increased sensitivity with hearing for the ear on the affected side of the face, or a slight pain behind that ear. Again, it is important to see a doctor if Bell’s palsy is present to rule out more serious disorders. However, time will generally restore the facial nerve to normal.
