Bell's Palsy: A Comprehensive Guide

Bell's Palsy is a condition that often raises more questions than answers. This guide is intended to demystify some of that uncertainty by providing clear, factual information on the condition, its common symptoms, potential causes, and various treatment options.

Dealing with Bell's Palsy can be challenging, but understanding what you're facing is the first step toward managing it effectively. With that in mind, let's delve into the different aspects of this condition to better equip you with the knowledge you need.

What Is Bell's Palsy or Facial Palsy?

An individual suffering from Bell's Palsy experiences the sudden weakness or paralysis of facial muscles. Named after the Scottish anatomist Sir Charles Bell, this condition manifests as the sudden drooping of one side of the face, making it challenging to control facial expressions. People with this condition may have a floppy appearance on one or both sides of the face. The inflammation of the seventh cranial nerve that regulates the facial muscles makes the face on one side appear droopy.

People with this condition may also have eyelids remaining open or asymmetrical smiles. The condition may last for several months and often goes away without treatment. Typically, men and women between fifteen and sixty years of age are prone to this condition. Permanent recovery from the condition may take about two weeks to six months from the appearance of symptoms, and only in rare cases, it stays for a lifetime.

Symptoms of Bell's Palsy or Facial Palsy

The symptoms of this condition appear suddenly and may peak within forty-eight to seventy-two hours. While in some people, the symptoms are mild. Others may experience complete paralysis. The symptoms may show improvement within two to three weeks, and about eighty percent of people recover fully within three months. The symptoms of the condition are:

Facial Drooping

One of the most apparent signs of Bell's Palsy is facial drooping, primarily affecting one side. This sudden sagging often prompts individuals to seek immediate medical attention, which can be alarming and uncomfortable.

Difficulty Closing the Eye

Muscle weakness can make it challenging to close the eye on the affected side fully. This can be problematic, exposing the eye to potential irritation and injury.

Loss of Taste

Many people experience an altered or diminished sense of taste, mainly affecting the front two-thirds of the tongue. This change can make eating less enjoyable and may impact overall nutrition.

Increased Sensitivity to Sound

Known as hyperacusis, this condition can make even moderate sounds seem unbearably loud or jarring. The increased sensitivity usually affects the ear on the same side as the other Bell's Palsy symptoms.

Excessive Tearing or Dry Eye

People with Bell's Palsy may notice inconsistencies in tear production. Some might have an overflow of tears, while others experience dryness, requiring attention to prevent eye complications.

Impaired Speech

The facial muscle weakness associated with Bell's Palsy may also affect speech, making it harder to articulate words clearly. This can be frustrating and may lead to misunderstandings during conversations.


Weakened facial muscles may also result in drooling, which can be uncomfortable and socially awkward for those experiencing it.

Difficulty in Eating and Drinking

Reduced muscle control on one side of the face can make it difficult to eat and drink, sometimes leading to spills and decreased nutritional intake.

Dryness in the Mouth

Some people may experience dryness in the mouth, making swallowing difficult and leading to dental issues over time.

Headache and Sensitivity to Sound

Headaches, often accompanied by heightened sensitivity to sound, can add a layer of discomfort for those dealing with Bell's Palsy.

Tinnitus or Ringing in the Ears

A less common but disruptive symptom is tinnitus, which can manifest as ringing, buzzing, or hissing sounds in the ears.

The symptoms of this condition may have similarities with other medical problems, so it is best to discuss them with a doctor.

Causes of Bell's Palsy or Facial Palsy

Although the exact cause of Bell's Palsy remains elusive, various factors and conditions may trigger or exacerbate the symptoms. The estimated causes of this condition are:

Viral Infections

Herpes Simplex Virus: Commonly responsible for cold sores and genital herpes, this virus has been linked to some cases of Bell's Palsy.

Epstein-Barr Virus: Known for causing mononucleosis, this virus may also be a potential trigger for the condition.

Herpes Zoster Virus: The virus behind chickenpox and shingles could play a role in the onset of Bell's Palsy.

Cytomegalovirus Infections: These infections have been occasionally connected to this facial paralysis condition.

Respiratory Diseases Through Adenovirus: Conditions like the common cold or respiratory infections may contribute to the onset of Bell's Palsy.

German Measles (Rubella): Although rare, rubella has been sometimes considered a potential cause.

Flu: Influenza can weaken the immune system, potentially setting the stage for Bell's Palsy.

Hand-Foot-And-Mouth Disease: While uncommon, this viral illness has been linked to some cases.

Mumps: Another viral illness that could act as a trigger, although the evidence is not strong.

Other Medical Conditions

Hypertension: High blood pressure can cause various health issues, possibly contributing to Bell's Palsy.

Diabetes: Diabetics are more likely to suffer circulatory problems due to inflammation.

Sarcoidosis: This inflammatory disease can affect various organs and may be a contributing factor.

HIV: A compromised immune system could make one more susceptible to Bell's Palsy.

Myasthenia Gravis: This neuromuscular disorder can affect facial muscles and overlap with Bell's Palsy symptoms.

Lyme Disease: The bacterial infection caused by ticks has been linked to facial paralysis in some cases.

Multiple Sclerosis: A disease affecting the central nervous system and can potentially cause facial paralysis.

Toxins: Exposure to certain harmful substances may contribute to the condition's onset.

Injury: Trauma to the face or head can directly affect the facial nerves and may lead to Bell's Palsy.

Neurofibromatosis: A genetic disorder that can cause tumors on nerve tissues, potentially affecting the facial nerve.

Ramsay Hunt Syndrome: This condition can cause facial paralysis and is often associated with a painful rash.

Surgical Removal of Facial Nerve Tumor or Acoustic Neuroma: Surgery in this sensitive area can result in nerve damage that leads to Bell's Palsy.

Understanding these potential causes can aid in early diagnosis and influence the treatment plan. However, it's essential to consult healthcare professionals for an accurate diagnosis and tailored management of Bell's Palsy.

Treatment Options for Bell's Palsy: A Closer Look

Understanding your treatment options is vital when dealing with Bell's Palsy. Here we break down what you can expect:


Corticosteroids: These drugs help to reduce swelling around the facial nerve and are often the first treatment offered.

Antiviral Medications: These may be prescribed alongside corticosteroids if a viral infection is suspected.

Other Treatment Options

Physical Therapy:  Specific physical therapy exercises can help you regain muscle control in your face. 

Lubricating Eye Drops or Ointments: These can help if you have a dry eye or trouble closing it fully to prevent damage.

Surgery (Rare Cases): Surgical Procedures: Surgery is rarely needed but can relieve pressure on the facial nerve in extreme cases.

When to See a Physiotherapist for Bell's Palsy or Facial Palsy?

A scheduled visit to the physical therapist's clinic is helpful during the first couple of days when the symptoms show. The therapist reviews the person's medical history and discovers the underlying conditions and previous surgeries. They also evaluate the present symptoms and what may improve or worsen them. The therapist:

  • Educates the person about how to protect the eye and face
  • Shows ways to manage daily life with facial paralysis
  • Explain the path to recovery after assessing the symptoms

Exercises and therapy restore muscle strength and help regain facial coordination faster. The exercises must be done about three to four times a day, with about twenty to thirty repetitions for each exercise. The exercises are:

  • Facial stimulation
  • Nose and cheek exercises to remove the stiffness from these areas
  • Mouth exercises to promote ease of eating & drinking and regain better control of the mouth
  • Eye exercises to aid the muscle movement around the eyes

All exercises for this condition can be practiced safely and without supervision at home. However, overexertion of the muscles needs to be avoided. In case of muscle pulling during exercises, it is essential to allow them to relax.

Risks of Bell's Palsy or Facial Palsy

Mild symptoms of the condition disappear without treatment, although the recovery time may differ. The complications are:

  • Excessive damage to the facial nerve
  • Partial or complete blindness when the eye does not close due to dryness and the removal of the protective covering or cornea
  • Regrowth of the nerve fibers may be abnormal, and the eye on the affected side may close during smiling.

Related Conditions

The related conditions are all associated with viral diseases, so treating the symptoms of viral infections can help. Most people recover from the symptoms unless the cause is more serious, such as nerve damage due to cerebral stroke.
