Bell’s Palsy: Causes, Symptoms & How Physiotherapy Can Help Recovery

Sudden facial drooping or paralysis may be Bell’s palsy. Learn the causes, common symptoms, treatment options, and how physiotherapy supports facial muscle recovery. Early assessment matters. Visit Wellbeing Physiotherapy in West Leederville.

Understanding Bell’s Palsy

Bell’s palsy is a condition that leads to temporary weakness or paralysis on one side of the face. It occurs when the facial nerve (Cranial Nerve VII) becomes inflamed or compressed, interrupting its ability to control normal expression, blinking, smiling and eating.

Although symptoms develop very quickly and may feel concerning, Bell’s palsy is usually temporary, with most people recovering fully.

What Causes Bell’s Palsy?

The most common cause is a viral infection that triggers inflammation near the facial nerve — frequently the:

• Herpes simplex virus (cold sores)

• Varicella-zoster virus (shingles)

Other potential contributors include:

• Exposure to cold wind or air conditioning

• Recent respiratory illness

• Stress, fatigue or weakened immunity

• Pregnancy (late stages)

Bell’s palsy is not a stroke, but immediate medical assessment is essential to rule out other causes of facial paralysis.

Symptoms to Look Out For

Symptoms often appear overnight and can include:

• Drooping or reduced movement on one side of the face

• Difficulty closing the eye or blinking

• Dribbling when drinking or speaking

• Facial tightness, redness or swelling

• Changes in taste

• Increased sensitivity to sound on one side

The unaffected side may look more active, giving the impression of the face being pulled sideways.

Physiotherapy for Bell’s Palsy: Restoring Facial Function

Physiotherapy plays a key role in helping the facial nerve reconnect with the muscles, enhancing both function and symmetry throughout recovery.

At Wellbeing Physiotherapy, treatment is tailored to each individual and may include:

• Assessment of specific muscle weakness and movement patterns

• Neuromuscular re-education to restore coordinated facial movements

• Gentle activation and stimulation (including ice facilitation)

• Mirror therapy to improve awareness and symmetry

• Strategies to protect the eye while blinking remains weak

• Progressive home exercise program with support at each stage

These methods help prevent long-term issues such as synkinesis, where unintended muscles activate during movement (e.g., eye closing when smiling).

Expected Recovery

The outlook is very positive:

• 70–85% of people recover completely within 3–6 months

• Best outcomes occur when medical treatment + physiotherapy begin early

• Consistency with guided exercises enhances healing

Regular review ensures rehabilitation adapts as the nerve recovers.

When to Seek Help

Sudden facial weakness should always be treated as urgent — seek medical attention immediately.

After diagnosis of Bell’s palsy, seeing a physiotherapist promptly helps maximise recovery and confidence.
