A normal functioning facial nerve allows us to move our face and neck (smile, frown, wrinkle our nose and forehead), secrete saliva, lets the front of the tongue "taste" food, and makes us cough when something is placed in the ear.
Anything that may cause swelling or pressure on the nerve can result in abnormal function.
Problems with the facial nerve result in weakness or paralysis of the face muscles and possibly, a loss of taste on the affected side. This nerve loss is one of the most disfiguring since it involves facial movement. Without the nerve connection (innervation) intact, the eye does not close, there is loss of facial muscle tone, and movement on the affected side is reduced or lost.
In other words.... please go get it checked out.
