  • The most common symptom of Bell’s palsy is the sudden weakness or paralysis on one side of your face causing it to droop. 
  • Drooling.
  • Eye issues such as excessive tearing or a dry eye.
  • Altered taste.
  • difficulty eating and drinking

What are the causes of Bell’s palsy and what Is the main cause of Bell’s palsy ?

  • Chickenpox and shingles (herpes zoster)
  • Mumps

  • Sarcoidosis

What is the best cure for Bell’s palsy and what happens If Bell’s palsy Is untreated?  

Most people with Bell’s palsy fully recover even without treatment. But some medications or physiotherapy can help speed up Bell’s palsy recovery. Some studies showed that about one third of untreated Bell’s Palsy patients suffered from long term effects such as facial spasms and disfigurement, and chronic pain. 

The best Bell’s palsy treatment will vary between individuals but most will be prescribed corticosteroids to reduce the facial nerve inflammation of the facial nerves. Some patients may be prescribed antiviral drugs like acyclovir to speed up the recovery process.

What Is The Best Treatment For Bell’S Palsy?

Bell’s palsy improves without treatment. Still, your healthcare provider may recommend one or more of these therapies for symptom relief and a faster recovery:

Another effective Bell’s palsy treatment is eye care which is crucial in protecting the eyes from injuries and irritants. If your eye does not close completely, the use of glasses or goggles is beneficial.  An eye patch can be used at night. 

Decompression surgery to ease nerve pressure eases pressure but it is rarely done because it may cause permanent nerve damage and loss of hearing.

Another beneficial treatment for Bell’s Palsy is Physiotherapy.

A registered physiotherapist can assist with providing education and support during recovery in order to reduce secondary complications. 

  • Electrical muscle stimulation is used to stimulate the nerve fibers in order to help maintain some of the strength, which then promotes faster recovery,
  • Daily exercise regimen
  • Soft tissue massage can be applied to the head and face to help with aches and help stimulate repair of innervation for the facial muscles.

Recovery from Bell’s Palsy

In general, people whose paralysis is less severe tend to start to improve with or without treatment after a few weeks, with complete recovery of facial function within six months. If symptoms start to improve within the first 21 days, chances are there will be complete recovery with no residual facial muscle weakness.

At Physiotherapy Oakville, we understand the importance of early intervention and personalized care in facilitating recovery. Scientific studies have shown that timely physiotherapy can enhance the recovery process for facial paralysis, minimizing residual muscle weakness and improving overall outcomes. By joining Physiotherapy Oakville, you gain access to expert physiotherapists who provide evidence-based treatments tailored to your specific condition, supporting a faster and more complete recovery.

What are the complications Of Bell’s palsy?

Some of the complications of Bell’s palsy are:

  • Irregular regrowth of nerve fibers and irreversible damage to your facial nerve which can result in synkinesis.  Synkinesis is a condition in which moving one part of your face causes involuntary contraction of another.
  • Excessive eye dryness on your affected side, which can lead to eye infections or even vision loss.
  • Some people don’t fully recover and are left with long term facial paralysis and drooping.

Bell’s Palsy versus Stroke


The cause of Bell’s palsy is uncertain but some viruses like herpes zoster, herpes simplex, and mumps have been believed to be connected to Bell’s palsy.

Stroke is caused by high blood pressure, heart disease, high cholesterol, previous stroke.


Bell’s palsy does not require any specific testing. Your doctor may ask you to perform specific facial movements such as eyebrow raising, frowning, smiling, and eyes closing. At times, EMG or MRI may be conducted to rule out stroke.

Diagnosing strokes is dependent on several factors. Some imaging scans are used to assess the brain and its blood supply.


Treatment of Bell’s palsy are corticosteroids and antiviral medications, pain medications, and physiotherapy.

There is a more complex approach in treating stroke and its treatment is dependent on the type of stroke.
