Bell's Palsy

What is Bell's palsy?

Bell’s palsy is a condition that causes sudden weakness or paralysis of the muscles on one side of the face, often without a clear cause. Although it can be alarming, Bell’s palsy is typically temporary, with most people recovering fully over time. Physiotherapy plays an important role in managing the condition—helping to stimulate the facial muscles, improve mobility, and support recovery.

What causes Bell's palsy?

The exact cause of Bell’s palsy is unknown, but it is believed to be linked to viral infections. The cold sore virus (herpes simplex) is a common suspect, as it can lie dormant in the facial nerve and become reactivated. Other viruses, such as those responsible for chickenpox (varicella-zoster) and shingles, may also trigger the condition. If you're experiencing symptoms of Bell’s palsy, physiotherapy can support your recovery.

What are the symptoms of Bell's palsy?

The onset of Bell's palsy is typically sudden, developing over the course of a few hours or overnight. The primary symptom is weakness or complete paralysis on one side of the face. This facial paralysis can lead to:

  • A drooping appearance on one side of the facev
  • Difficulty closing the eye or blinking
  • Drooling or trouble controlling saliva
  • Loss of facial expressions, such as smiling or frowning
  • Altered taste sensation
  • Sensitivity to sound in one ear (hyperacusis)
  • Dry eye or excessive tearing

Around 80% of people with Bell’s palsy recover fully within three weeks. The remaining 20% typically notice gradual improvement over a period of 3 to 6 months, as the affected facial nerve slowly regenerates. Early intervention, including physiotherapy, can help optimise recovery and reduce long-term complications.

What should I do if I have Bell's palsy?

If you suspect that you may have Bell’s palsy, it’s important to see your GP as soon as possible. Early diagnosis and treatment can help improve recovery and rule out other more serious conditions.

What shouldn't I do if I have Bell's palsy?

If you suspect you have Bell’s palsy, do not ignore the symptoms. Prompt medical attention is essential to maximise your chances of a full recovery. Early treatment—often including medication and physiotherapy—can significantly improve outcomes and reduce the risk of long-term complications.

Medical treatment for Bell's palsy

Your doctor will typically be able to diagnose Bell’s palsy by assessing your symptoms and examining your facial movements. In some cases, they may perform additional tests—such as blood work or imaging scans—to rule out other possible causes of facial paralysis, such as stroke or infections.

Treatment for Bell’s palsy varies between individuals, but most patients are prescribed a short course of corticosteroids to reduce inflammation of the facial nerve. In some cases, antiviral medication may also be recommended, particularly if a viral infection is suspected as the trigger.

  • Regularly close the eye by pulling the upper lid down with your finger.
  • Wear protective glasses or an eye patch.
  • Tape the eye closed before you go to sleep.
  • Use artificial tears (eye drops) to keep the eye moist - ask a pharmacist for advice.

Physiotherapy treatment for Bell's palsy

Physiotherapy plays a vital role in the recovery from Bell’s palsy. The experienced physiotherapists at Ace Physio Sports can provide you with:

  • Personalised facial exercises to improve muscle strength and coordination
  • Hands-on techniques to stimulate facial nerve activity
  • Guidance on relaxation techniques to reduce tension in unaffected muscles
  • Advice on eye care and facial protection during recovery
  • Ongoing monitoring to track progress and adjust treatment as needed

The primary aim of physiotherapy for Bell’s palsy is to stimulate the affected nerve fibres and support their recovery. One effective method is the use of Electrical Muscle Stimulation (EMS), which helps activate the facial nerves and maintain muscle tone during the early stages of paralysis. This stimulation can encourage faster recovery once the nerves begin to regenerate. As your muscle strength improves, your physiotherapist will guide you through progressive facial exercises designed to further strengthen and coordinate the facial muscles, enhancing overall function and symmetry.

Does Bell's palsy have any long-term effects?

In a small number of cases, Bell’s palsy can lead to long-term or permanent facial muscle paralysis. For individuals affected in this way, there are several specialist treatment options that may help improve function and appearance. These should be discussed with a qualified healthcare professional and may include:

  • Advanced physiotherapy techniques for muscle retraining
  • Botulinum toxin (Botox) injections to manage unwanted muscle activity
  • Surgical procedures, such as nerve grafts or muscle transfers
  • Psychological support to manage the emotional impact of long-term symptoms
