What is Bell's palsy?
Bell's palsy is a sudden weakness or paralysis of the muscles on one side of the face, caused by inflammation of the facial nerve. It usually appears over a few hours to a couple of days. The exact trigger is often unclear, though viral inflammation is the most accepted explanation. It is not a stroke, the facial nerve itself is affected, not the brain, but only a doctor can make that distinction safely, which is why the first stop is always medical assessment.
Common symptoms
- Drooping of one side of the face, with a flattened smile on that side
- Inability to close the eye fully or raise the eyebrow on the affected side
- Drooling or difficulty holding water in the mouth while rinsing
- Altered taste on the front of the tongue
- Sensitivity to loud sounds in one ear
- Aching around the jaw or behind the ear, sometimes a day or two before the weakness
What causes it?
The facial nerve travels through a narrow bony canal behind the ear. When the nerve swells, usually after a viral infection, that canal compresses it, and the signals to the facial muscles are interrupted. Diabetes, pregnancy and recent viral illness raise the risk. Cold air exposure is a popular local explanation; the evidence points to inflammation rather than the ceiling fan, but the treatment path is the same either way.
Red flags: rule out stroke first
Bell's palsy affects the face only. If facial drooping comes with arm or leg weakness, slurred speech, double vision, severe headache, dizziness or difficulty swallowing, treat it as a possible stroke and go to an emergency department immediately. Also see a doctor promptly if facial weakness develops slowly over weeks, keeps worsening after two weeks, or comes with hearing loss or a lump near the ear. These patterns need investigation and are not typical Bell's palsy.
How physiotherapy helps facial recovery
Doctors usually prescribe a short course of steroids in the first days, that part is medical. Physiotherapy then takes over the recovery of movement:
- Facial neuromuscular re-education: precise, mirror-guided exercise therapy for the forehead, eye, cheek and mouth muscles, taught in the correct sequence and dosage. Quality matters more than force; over-exercising a recovering nerve can encourage unwanted muscle linkages.
- Electrotherapy where appropriate: modalities from our electrotherapy toolkit can support muscle activity and comfort during recovery, chosen case by case after assessment.
- Massage and stretching: gentle facial massage keeps the muscles supple while the nerve heals, and helps manage tightness on the unaffected side that develops from overuse.
- Synkinesis prevention: as the nerve regrows, wires can cross, the eye winks when you smile, for example. Early guided retraining reduces the chance of these faulty patterns setting in.
Bell's palsy treatment at Physio Buddy
Dr. Maitri Kothari (BPT, MPT) holds an advanced certification in neurological physiotherapy, and facial palsy rehab is a regular part of her neuro caseload. Your first session includes a grading of facial muscle function, eye closure assessment, and a personalised exercise chart with photographs of each movement, so home practice is never guesswork. Most patients attend our Chandkheda clinic once or twice a week and do a short exercise routine at home twice daily. If travel is difficult, we offer home visits across North Ahmedabad and virtual consultations to check your exercise technique on video.
Protecting the eye
Until the eyelid closes fully, the eye cannot protect itself. We guide you on lubricating drops during the day, ointment and taping or an eye patch at night, and sunglasses outdoors. Any eye redness, pain or blurring should go straight to an eye specialist.
Simple starter exercises
Do these in front of a mirror, slowly, 5 to 10 repetitions each, two or three times a day, and stop at the first sign of fatigue. Have your technique checked before making them routine.
- Raise your eyebrows gently, assisting the weak side with two fingers if needed, and hold for 3 seconds.
- Close the eyes slowly and softly, without clenching the strong side.
- Attempt a gentle closed-lip smile, keeping both corners as even as you can.
- Puff the cheeks lightly and hold the air for 3 seconds; do not force if air leaks.
- Purse the lips as if sipping through a straw.
Recovery timeline
Most people notice the first flickers of returning movement within 2 to 3 weeks, and around 70 to 80 percent recover fully or almost fully within 3 to 6 months, especially when treatment starts early. Recovery that begins late or is incomplete at 3 months benefits most from structured retraining, this is where physiotherapy earns its keep, refining symmetry and preventing synkinesis rather than just waiting. A small minority have residual weakness beyond a year; even then, targeted exercises improve function and confidence.

Frequently Asked Questions
How do I know it is Bell's palsy and not a stroke?
You cannot know for certain at home, so any sudden facial droop deserves urgent medical assessment. As a rule of thumb, Bell's palsy affects the face only, including the forehead, while a stroke usually spares the forehead and brings other signs like arm weakness or slurred speech. Let a doctor confirm the diagnosis first; physiotherapy comes after that.
When should physiotherapy start for Bell's palsy?
Once a doctor has confirmed the diagnosis and started medical treatment, physiotherapy can begin within the first week. Early sessions focus on gentle activation, eye protection and preventing bad habits, and the programme progresses as the nerve recovers.
Will my face recover completely?
Most people do very well. Roughly 70 to 80 percent recover fully or nearly fully within 3 to 6 months, and early, correct treatment improves the odds. A smaller group has slower or partial recovery, which is exactly where guided retraining matters most, so we monitor progress and adjust the plan rather than leaving recovery to chance.
Can I do facial exercises on my own from YouTube?
Some movement practice is better than none, but unsupervised over-exercising is a real problem in facial palsy. Forcing strong contractions on a recovering nerve can wire faulty patterns, like the eye closing whenever you smile. A short assessment gets you the right exercises at the right dose, which you then do independently at home.
Is electrotherapy useful for Bell's palsy?
It can play a supporting role in selected cases, alongside exercise retraining, which remains the core of treatment. We assess each patient individually and explain what we recommend and why. Ask us what fits your case.
Do you treat Bell's palsy at home?
Yes. If travelling to our Chandkheda clinic is difficult, we arrange home visits across Chandkheda, Motera, Gandhinagar and nearby North Ahmedabad, and virtual follow-ups work well for checking exercise technique between visits.
