Bell’s palsy causes sudden, temporary weakness in your facial muscles. This makes half of your face appear to droop. Your smile is one-sided, and your eye on that side resists closing.
Bell’s palsy, also known as facial palsy, can occur at any age. The exact cause is unknown. It’s believed to be the result of swelling and inflammation of the nerve that controls the muscles on one side of your face. Or it might be a reaction that occurs after a viral infection.
For most people, Bell’s palsy is temporary. Symptoms usually start to improve within a few weeks, with complete recovery in about six months. A small number of people continue to have some Bell’s palsy symptoms for life. Rarely, Bell’s palsy can recur.
Signs and symptoms of Bell’s palsy come on suddenly and may include:
- Rapid onset of mild weakness to total paralysis on one side of your face — occurring within hours to days
- Facial droop and difficulty making facial expressions, such as closing your eye or smiling
- Pain around the jaw or in or behind your ear on the affected side
- Increased sensitivity to sound on the affected side
- A decrease in your ability to taste
- Changes in the amount of tears and saliva you produce
In rare cases, Bell’s palsy can affect the nerves on both sides of your face.
When to see a doctor
Seek immediate medical help if you experience any type of paralysis because you may be having a stroke. Bell’s palsy is not caused by a stroke, but it can cause similar symptoms.
See your doctor if you experience facial weakness or drooping to determine the underlying cause and severity of the illness.
Although the exact reason Bell’s palsy occurs isn’t clear, it’s often related to exposure to a viral infection. Viruses that have been linked to Bell’s palsy include the virus that causes:
- Cold sores and genital herpes (herpes simplex)
- Chickenpox and shingles (herpes zoster)
- Infectious mononucleosis (Epstein-Barr)
- Cytomegalovirus infections
- Respiratory illnesses (adenovirus)
- German measles (rubella)
- Mumps (mumps virus)
- Flu (influenza B)
- Hand-foot-and-mouth disease (coxsackievirus)
The nerve that controls your facial muscles passes through a narrow corridor of bone on its way to your face. In Bell’s palsy, that nerve becomes inflamed and swollen — usually related to a viral infection. Besides facial muscles, the nerve affects tears, saliva, taste and a small bone in the middle of your ear.
Bell’s palsy occurs more often in people who:
- Are pregnant, especially during the third trimester, or who are in the first week after giving birth
- Have an upper respiratory infection, such as the flu or a cold
- Have diabetes
Recurrent attacks of Bell’s palsy are rare. But in some of these cases, there’s a family history of recurrent attacks — suggesting a possible genetic predisposition to Bell’s palsy.
A mild case of Bell’s palsy normally disappears within a month. Recovery from a more severe case involving total paralysis varies. Complications may include:
- Irreversible damage to your facial nerve
- Abnormal regrowth of nerve fibers, resulting in involuntary contraction of certain muscles when you’re trying to move others (synkinesis) — for example, when you smile, the eye on the affected side may close
- Partial or complete blindness of the eye that won’t close due to excessive dryness and scratching of the clear protective covering of the eye (cornea)
Most people with Bell’s palsy recover fully — with or without treatment. There’s no one-size-fits-all treatment for Bell’s palsy, but your doctor may suggest Acupuncture to help speed your recovery.
According to Chinese Medicine, Bell’s Palsy is considered to be something called Zhong Feng, or an attack of wind. Similar to a cold or the flu. Bell’s Palsy is the result of external wind due to depletion. Simply meaning, that it comes from outside of your body (a virus) and flares up because you’re run down. Over the course of months or even years, behaviors like not eating well, working too hard, not resting or sleeping well, and stress wear you down to the point that pathogens move in, take hold, and make you sick.
Chinese Medicine views the body holistically and treats disease based on patterns of systems of function. In Bell’s Palsy we focus on the main manifestation of paralysis, sensations of heaviness and pain, as well as underlying functional issues such as fatigue and poor sleep. Acupuncturists aim to restore facial function by decreasing inflammation, restoring normal circulation to the face, and supplementing the body’s normal repair mechanisms.
With acupuncture is the primary therapy, we can directly stimulate the affected muscles, reducing inflammation and increasing circulation, as well as using distal points on the body to build the body’s immune system back up and address the stress associated with the condition.
Lifestyle and home remedies
Home treatment may include:
- Protecting the eye you can’t close. Using lubricating eyedrops during the day and an eye ointment at night will help keep your eye moist. Wearing glasses or goggles during the day and an eye patch at night can protect your eye from getting poked or scratched.
- Taking over-the-counter pain relievers. Aspirin, ibuprofen (Advil, Motrin IB, others) or acetaminophen (Tylenol, others) may help ease your pain.
- Doing your physiotherapy exercises. Massaging and exercising your face according to your physical therapist’s advice may help relax your facial muscles.
