Top of the page Check Your Symptoms. Facial problems can be caused by a minor problem or a serious condition. Symptoms may include pain, swelling, or facial weakness or numbness. You may feel these symptoms in your teeth, jaw, tongue, ear, sinuses, eyes, salivary glands, blood vessels, or nerves. Common causes of facial problems include infection, conditions that affect the skin of the face, and other diseases. Treatment depends on what is causing your facial problem.
Medication for Facial Nerve Paralysis
Edematous swelling of the facial nerve in Bell's palsy.
Bell's palsy is a sudden weakness or paralysis on one side of the face that makes it hard for a person to move the mouth, nose, or eyelid. It also can make that side of the face droop or look stiff. Bell's palsy happens when a facial nerve is not working as it should, often after a virus. When they are working properly, they carry many messages from the brain to the face. These messages may tell an eyelid to close, one side of the mouth to smile or frown, or salivary glands to make spit. But if a nerve swells and is compressed, as happens with Bell's palsy, these messages don't get sent correctly.
Edematous swelling of the facial nerve in Bell's palsy.
Melkersson-Rosenthal Syndrome MRS is a rare otoneurologic condition, which is poorly understood and often underdiagnosed. Etiology and incidence are unclear, although infectious, inflammatory, and genetic causes have been implicated. Recurrent facial nerve palsy, facial swelling, and fissured tongue are the symptoms and signs of this condition.
There's no specific test for Bell's palsy. Your doctor will look at your face and ask you to move your facial muscles by closing your eyes, lifting your brow, showing your teeth and frowning, among other movements. Other conditions — such as a stroke, infections, Lyme disease and tumors — can also cause facial muscle weakness, mimicking Bell's palsy.
