Face Drooping One Side (Munh Tedha): Bell’s Palsy or Stroke?
Any new drooping of one side of the face is a stroke until a doctor proves otherwise: note the time it started and get to a hospital now, calling 1122 in Pakistan or 112 in India. Many of these turn out to be Bell’s palsy, a far less dangerous nerve problem, but you can’t be sure at home, and both do better with fast care.
Before anything else
- Now: new one-sided face droop means hospital now. Note the time it began.
- Don’t: wait to see if it passes, give food, water or pills, or visit a hakeem first.
- The eyebrow check: helps families describe it, never delays the trip.
- Bell’s palsy: a facial nerve inflammation; most people recover over weeks to months.
- Home job: protect the eye that can’t close.

Face drooping on one side: treat it as a stroke first
Here’s why speed matters. A stroke is a blocked or burst blood vessel in the brain, and for the blocked kind hospitals can give clot-busting treatment or pull the clot out, but only within a few hours of the start, so the first question the emergency team will ask, before scans and before anything else, is simple: when was the person last seen normal? So write down the time, or remember it exactly. If it happened in the night, the time counts from when they went to sleep.
Call 1122 or 112, or go to the nearest hospital with a CT scanner if an ambulance would be slower. While you get ready:
- Keep the person sitting or lying on their side, calm, and with you.
- Give nothing to eat or drink, and no medicine, not even aspirin. Swallowing may be affected, and some strokes are bleeds.
- Bring their medicine list, or the boxes, and any sugar or BP readings.
- If they are diabetic and a glucometer is at hand, check sugar quickly, because very low sugar can mimic a stroke; still go to hospital.
The full BE FAST signs (balance, eyes, face, arms, speech, time) are in falij (stroke) symptoms. Learn them once with the family.
Time lost at home can’t be given back in hospital. Go first, find out later.
Bell’s palsy vs stroke: the eyebrow raise
There is a well-known bedside difference, and it’s useful because it tells families what to watch for and what to tell the doctor. It must not become a reason to stay home.
- In the car or while waiting, ask the person to raise both eyebrows, as if surprised.
- Then ask them to close both eyes tight.
- Then ask them to smile and show their teeth.
- Finally, ask them to hold both arms out in front for 10 seconds with eyes closed, and to repeat a simple sentence.
| What you see | More like Bell’s palsy | More like stroke |
|---|---|---|
| Forehead on the weak side | Won’t wrinkle | Usually still wrinkles |
| Eye on the weak side | Won’t close fully | Usually closes |
| Arm, leg, speech | Normal | Often weak, numb, slurred or confused |
| How it came on | Over hours, often with ear ache or taste change | Often within minutes |
Why? The face muscles are wired from the brain through the facial nerve. The forehead gets signals from both sides of the brain, so a stroke on one side often spares it. Bell’s palsy damages the nerve itself further down, after the wires have joined, so the whole half of the face goes weak, forehead included. But some strokes don’t follow the rule, and a few other conditions (ear infections, shingles near the ear, tumours, Lyme disease) also cause droop. That’s exactly why a doctor must see it.
What Bell’s palsy is (and what it isn’t)
Bell’s palsy is a sudden weakness of one facial nerve, thought to come from swelling of the nerve inside its narrow bony channel, often after a viral infection. It usually builds over a day or two. People notice a crooked smile, dribbling of tea from one corner, food catching in the cheek, an eye that won’t shut, a dry or watering eye, ache behind the ear, sounds that seem too loud, or a change in taste on that side.
It’s more common in pregnancy and in people with diabetes. Any age, though. The good news is real: most people recover fully or almost fully over weeks to a few months, with the first signs of movement often within three weeks. A smaller group are left with some weakness or twitching.
Why the same-day visit still matters
Doctors often prescribe steroid medicine for Bell’s palsy, and it works best started within the first 72 hours. That’s a doctor’s decision after examining the person, never something to take from a neighbour’s leftover strip. So even when the family is sure it’s “only” Bell’s, the hospital today is the right answer.
For people with diabetes or high blood pressure, a new facial droop needs the full stroke work-up regardless. Keep taking every prescribed medicine as usual unless the doctor changes it; don’t stop, start or double anything on your own. A BP reading of 180/120 or above with any new symptom is itself an emergency.
Myth: thandi hawa, the fan, or “air in the face” causes it
In many homes the first explanation, offered by an aunt before anyone has even called the doctor, is that the person slept with the fan or AC blowing straight on their face all night, or went out on the motorbike in cold December wind without covering their ears. The honest picture: Bell’s palsy often appears overnight, so people wake with it after a night under the fan, and cold wind often goes with a cold, which is a real trigger. The timing makes the fan look guilty. Cold air on the face doesn’t paralyse a nerve by itself.
Other myths with real costs:
- Oil massage and heat won’t straighten the nerve, and hot compresses on a numb face can burn it.
- Threads, taweez, or tying the jaw do nothing for the nerve and waste the first days.
- A hakeem’s electric massage or strong stimulation early on isn’t shown to help and can tire the face. Physiotherapy advice from the hospital team is the safer route.
- “It’s only Bell’s, no hurry” is the most expensive myth of all, because it’s also what families say about strokes.
Unani texts describe laqwa, a twisting of the face, and linked it to cold and moisture. Families often turn to warm oils and keeping the face covered. Warmth is comforting, but none of it replaces the hospital visit in the first hours.
Protecting the eye at home
If the eye on the weak side can’t close, it dries and can be scratched without the person feeling it. This matters most.
- Ask a pharmacist for lubricating eye drops by day and a thicker eye ointment for night; the doctor or pack says how often.
- At night, close the lid gently with a clean finger and hold it with a strip of paper medical tape, or use an eye pad the hospital shows you how to fit. Never tape over an open eye.
- Wear glasses or sunglasses outdoors against dust and wind, and angle fans away from the face.
- Eat on the strong side, take small sips, and rinse the mouth after meals to clear food from the weak cheek.
- Gentle face exercises in front of a mirror only when the team suggests them.
A red, painful eye, blurred vision or discharge on the weak side needs an eye doctor quickly. For more household guides, see Desi Remedies.
Did you know?
The facial nerve also carries taste from the front of the tongue and controls a tiny muscle that dampens loud sounds, which is why some people with Bell’s palsy notice food tastes odd and everyday noise seems harsh.
The face droops suddenly on one side, especially with arm or leg weakness, numbness, slurred or confused speech, vision loss, severe headache, or loss of balance. Don’t wait for it to settle, don’t give food, drink or medicines, and don’t stop at a clinic without a scanner. Even with suspected Bell’s palsy, see a doctor the same day, because steroid treatment is time-limited. Get urgent help for droop in pregnancy, in a child, with a rash or blisters around the ear, with ear discharge, with fever, or when both sides of the face are weak. Never start, stop or change diabetes or BP medicines yourself.
Face drooping and Bell’s palsy: questions
Why is my face drooping on one side?
The two main causes are stroke and Bell’s palsy, and others exist. You can’t safely tell them apart at home, so any new one-sided droop means a hospital now.
How can I tell Bell’s palsy from a stroke?
In Bell’s palsy the forehead on the weak side won’t wrinkle and the eye won’t close; in a stroke the forehead usually still moves and there may be arm weakness or slurred speech. It’s a clue for the doctor, not a reason to stay home.
Bell’s palsy: when to see a doctor?
The same day it starts. Doctors need to rule out a stroke, and steroid treatment, if they choose it, works best within the first 72 hours.
Is Bell’s palsy serious?
It isn’t life-threatening, and most people recover over weeks to months. The risks are to the eye, which can be damaged if it can’t close, and missing a stroke that looked like Bell’s.
Can a fan or cold air cause Bell’s palsy?
Not by itself. It often appears overnight or after a cold, so the fan gets blamed. A viral infection is the more likely trigger.
What is droopy face not stroke?
Bell’s palsy is the commonest cause of a one-sided droop that isn’t a stroke. Ear infections, shingles near the ear and some rarer conditions also do it, which is why a doctor must examine the face.
How long does Bell’s palsy take to get better?
Many people see first movement within about three weeks and recover most function over three to six months. Some take longer or keep mild weakness.
Is there a Bell’s palsy home remedy?
No home remedy restores the nerve. The home work is eye protection, eating safely, and following the doctor’s plan. Oil massage and heat don’t help and can burn a numb face.
Munh tedha ho jaye to kya karein?
Note the time, call 1122 or 112, and go to a hospital with a scanner. Give nothing by mouth. Don’t go to a hakeem or wait to see if it passes.
Can children get Bell’s palsy?
Yes. A child with a new facial droop needs the same urgent hospital visit, as ear infections and other causes need ruling out.
Is Bell’s palsy more common in pregnancy or diabetes?
Yes, both raise the chance. Pregnant women and diabetics with a droop need a same-day doctor, and diabetics need a stroke check as well.
Should I tape my eye shut at night?
If the eye doesn’t close, yes: close the lid gently first, then hold it with paper medical tape or an eye pad, after ointment the pharmacist or doctor suggests. Never tape over an open eye.
Can Bell’s palsy come back?
It returns in a small minority, sometimes on the other side. A repeat still needs a same-day doctor.
