Bell's Palsy: Sudden Weakness on One Side of the Face
Drooping face or can't close one eye? How Bell's palsy differs from a stroke, why seeing a doctor within 72 hours matters, and how to protect your eye.
You look in the mirror and one side of your face won't move. Your smile is lopsided, water dribbles from one corner of your mouth, and one eye won't close. It's frightening, and many families immediately fear a "lakwa" (stroke). Often the cause is Bell's palsy, a sudden but usually temporary weakness of the facial nerve. Most people recover well, especially when treatment starts early.
Bell's Palsy or Stroke? Key Differences
| Bell's palsy | Stroke | |
|---|---|---|
| Forehead | Usually can't wrinkle the forehead on the weak side | Forehead often still moves |
| Eye | Can't close the eye fully on that side | Eye usually closes |
| Arm and leg | Normal | Often weak or numb on the same side |
| Speech | Words clear (lips may be clumsy) | Slurred, confused, or can't find words |
| Onset | Over hours to 2–3 days, often noticed on waking | Sudden, within minutes |
Other Signs of Bell's Palsy
- Pain behind the ear a day or two before
- Changed taste on one side of the tongue
- Sounds seem louder in one ear
- A watery eye, or a dry eye that stings
- Food collecting in the cheek, drooling
It's caused by swelling of the facial nerve, often after a viral infection. It's more common in pregnancy, diabetes, and after a cold. A painful rash or blisters in or around the ear with face weakness suggests a related condition (Ramsay Hunt syndrome) that needs antiviral treatment quickly.
The Eye Is the Priority
When the eyelid can't close, the eye dries out and can get scratched. That damage can last longer than the palsy itself.
- Lubricating eye drops in the day, and an eye gel or ointment at night (as your doctor advises)
- At night, gently tape the eyelid closed or use an eye pad
- Glasses or sunglasses outdoors against dust and wind
- Get help quickly if the eye becomes red, painful, or your vision blurs
Recovery: What to Expect
Most people start improving within 2–3 weeks, and the majority recover fully within 3–6 months. Early steroid medicine prescribed by a doctor helps. Gentle facial exercises shown by a doctor or physiotherapist can help as movement returns. If there is no improvement at all after 3 weeks, go back to your doctor.
Myth vs Fact
| Myth | Fact |
|---|---|
| "AC ki thandi hawa lagne se chehra tedha ho gaya." | There's no good evidence that cold air causes it. It's nerve swelling, usually after a virus |
| "Every face droop is lakwa (stroke)." | Many are Bell's palsy, but because some are strokes, every one needs urgent checking |
| "Massage, hot oil or chewing gum will fix it fast." | They don't speed recovery. Early medicine and eye care matter most. Avoid strong rubbing |
| "It's permanent." | Most people recover fully, particularly with early treatment |
Before You Consult, Note These
- Exact time you first noticed it (this matters for the 72-hour window)
- Whether your arm, leg or speech are affected at all
- Ear pain, ear rash, or recent cold or fever
- Pregnancy, diabetes, or high blood pressure
- A short video of you raising your eyebrows, closing your eyes and smiling
If there are no stroke signs, an online video consultation can be a quick way to be assessed the same day and start treatment within the window. The doctor will tell you if you need to be seen in person. Seek emergency care immediately for any stroke warning signs. (See our stroke FAST guide and our headache guides.)
