Bell’s palsy is one of those sudden and scary health problems that can happen to anyone. Imagine waking up one morning and noticing that one side of your face doesn’t move the way it should — your smile looks uneven, your eye doesn’t close properly, or you can’t blink.
What is Bell’s Palsy?
Bell’s palsy is a sudden weakness or paralysis (loss of movement) on one side of the face. It happens because of inflammation or damage to the facial nerve (cranial nerve VII), which controls facial muscles.
This nerve helps you smile, blink, close your eyes, frown, and move your lips. When it stops working properly, your face on one side may droop or feel stiff.
Bell’s palsy usually appears suddenly — within hours or overnight. The good news is that most people start recovering within a few weeks and fully recover within 3–6 months.

Is Bell’s Palsy Dangerous?
Most of the time, Bell’s palsy is not dangerous. However, it can be frightening, especially because its symptoms look like those of a stroke.
The difference is that a stroke affects many parts of the brain and body, while Bell’s palsy affects only one facial nerve.
In rare cases, if the nerve damage is severe or not treated on time, some people may have lasting weakness or facial stiffness. That’s why early diagnosis and proper treatment are important.
What Triggers Bell’s Palsy?
Doctors are still researching the exact cause, but most agree that viral infections are the main trigger.
Some viruses that can cause Bell’s palsy include:
- Herpes simplex virus (the same virus that causes cold sores)
- Herpes zoster (causes shingles)
- Epstein-Barr virus (causes mononucleosis)
- Cytomegalovirus
- Adenovirus (common cold virus)
When the facial nerve becomes inflamed due to infection, it swells and gets compressed inside a narrow bone canal, leading to weakness on one side of the face.
Other possible triggers include:
- Stress or emotional pressure
- Cold exposure (sleeping in front of a fan or air conditioner)
- Autoimmune conditions
- Diabetes
- Pregnancy (especially in the third trimester)
Bell’s Palsy vs Stroke: How to Tell the Difference
Because both conditions affect facial muscles, people often confuse Bell’s palsy with a stroke.
Here’s how you can tell them apart easily:
| Feature | Bell’s Palsy | Stroke |
|---|---|---|
| Onset | Sudden (within hours) | Sudden (within seconds or minutes) |
| Side of Face | One side only | One side or both, often with limb weakness |
| Eye Movement | Cannot close one eye | Eye usually closes normally |
| Forehead Movement | Affected (can’t raise eyebrows) | Often normal |
| Other Symptoms | Ear pain, taste changes, dry mouth | Slurred speech, arm weakness, confusion, dizziness |
| Emergency? | Usually not life-threatening | Medical emergency |
Common Symptoms of Bell’s Palsy
Bell’s palsy symptoms usually appear suddenly, and they peak within 48 hours. The symptoms can vary from mild weakness to complete paralysis.
Main Symptoms
- Drooping on one side of the face
- Difficulty closing one eye
- Trouble smiling or frowning
- Drooling or leaking saliva
- Loss of taste on the front part of the tongue
- Pain behind the ear or jaw
- Sensitivity to loud sounds
- Dry eye or watery eye
- Difficulty eating or drinking
Less Common Symptoms
- Headache
- Tingling sensation on the affected side
- Twitching or muscle spasms
- Facial tightness
If both sides of your face are affected (rare), it may not be Bell’s palsy — other conditions like Lyme disease or Guillain-Barré syndrome should be checked.
Types of Bell’s Palsy
While Bell’s palsy is mainly a single condition, it can be categorized based on severity and underlying cause:
- Mild Bell’s Palsy: Slight weakness; full recovery expected within weeks.
- Moderate Bell’s Palsy: Noticeable weakness and facial droop; recovery may take a few months.
- Severe Bell’s Palsy: Complete paralysis on one side; may lead to long-term nerve damage if untreated.
- Recurrent Bell’s Palsy: When symptoms return after recovery, often triggered by viral reactivation or stress.
Causes of Bell’s Palsy
As mentioned, viral infection is the main cause. However, other contributing factors can include:
- Weak immune system
- Diabetes mellitus
- Ear infections
- Head or facial trauma
- Exposure to cold air or wind
- High blood pressure
- Inflammation due to autoimmune disease
How is Bell’s Palsy Diagnosed?
There’s no specific test for Bell’s palsy, but doctors diagnose it based on symptoms and physical examination.
Your doctor may:
- Examine your facial movements — asking you to smile, blink, or raise your eyebrows.
- Check your hearing and taste — to rule out other nerve problems.
- Perform imaging tests like:
- MRI or CT scan (to rule out stroke or tumor)
- Conduct nerve tests such as:
- Electromyography (EMG) — checks how well your facial nerves send signals to muscles.
These tests help confirm that the paralysis is due to Bell’s palsy and not something more serious.
Bell’s Palsy Treatment
Most people with Bell’s palsy start improving within 2–3 weeks and recover fully in 3–6 months, even without treatment.
However, early treatment helps reduce complications and speeds up healing.
1. Medications
- Corticosteroids (like Prednisone): Reduce nerve swelling and inflammation. Most effective if started within 72 hours of symptoms.
- Antiviral drugs (like Acyclovir or Valacyclovir): Sometimes used if a virus is suspected.
- Pain relievers: Ibuprofen or paracetamol can reduce pain behind the ear or jaw.
2. Eye Protection
Because the eye on the affected side may not close properly, it’s important to keep it moist and safe.
- Use lubricating eye drops or artificial tears.
- Wear an eye patch at night to prevent dryness.
3. Physical Therapy
- Gentle facial exercises can strengthen the muscles.
- A physiotherapist can guide you in doing massage and stimulation therapy.
4. Home Remedies
- Warm compress on the affected side
- Facial massage using circular motion
- Avoid cold wind exposure
- Eat soft foods and chew slowly
5. Surgical Option (Rare)
In rare, severe cases, doctors may recommend decompression surgery to relieve nerve pressure. However, this is rarely needed.
Bell’s Palsy Recovery Timeline
Recovery time varies from person to person:
| Recovery Stage | Duration | Details |
|---|---|---|
| Early Improvement | 2–3 weeks | Facial movement starts returning |
| Partial Recovery | 1–2 months | Most functions restored |
| Full Recovery | 3–6 months | Normal facial movement returns |
| Delayed Recovery | After 6 months | Some may have stiffness or incomplete recovery |
Bell’s Palsy Recovery After 2 Years
In rare cases, people may continue to have some effects even after 2 years, such as:
- Slight facial weakness
- Muscle tightness
- Uncontrollable facial movements (called synkinesis)
If recovery is incomplete after a long time, botulinum toxin (Botox) injections, physical therapy, or plastic surgery may help improve appearance and movement.
What to Avoid During Bell’s Palsy
While recovering, avoid the following to prevent worsening or slow healing:
- Sleeping with direct air from a fan or AC on your face
- Stress or overworking
- Skipping medication
- Rubbing or pressing the face too hard
- Eating hard or chewy food
- Ignoring eye protection
A healthy lifestyle, enough sleep, and good hydration help in faster healing.
Natural Ways to Support Recovery
In addition to medical treatment, natural remedies can support your recovery:
- Facial yoga: Helps improve facial symmetry and movement.
- Vitamin B12, B6, and Zinc: Boost nerve repair.
- Acupuncture: Some studies suggest it can improve muscle strength.
- Aloe vera massage: Reduces inflammation and soothes the skin.
Always discuss natural treatments with your doctor before trying them.
