Bell's Palsy: Symptoms, Diagnosis & Treatment
A clear guide to Bell's palsy, the sudden facial weakness it causes, how it is diagnosed, and the treatment that supports recovery.
Treatment usually begins with
Specialist Assessment
Facial Function Exam
Medical Management
Care Team Follow-up
Early evaluation and medication within the first few days give the best chance of full recovery.
You may need this evaluated if...
A Bell's palsy evaluation is recommended when these signs appear:
- Sudden weakness or drooping on one side of the face
- Difficulty closing one eye or smiling evenly
- Drooling or difficulty with facial expressions
- Symptoms appeared within the last day or two
Most cases of Bell's palsy improve with prompt treatment, but sudden facial weakness always needs urgent evaluation to rule out stroke.
What is Bell's Palsy?
Bell's palsy is a sudden, temporary weakness or paralysis of the muscles on one side of the face, caused by inflammation of the facial nerve.
Sudden Onset
Weakness typically develops over hours to a day or two.
One-Sided
Affects one side of the face, unlike a stroke which has broader symptoms.
Usually Temporary
Most people recover significant function within weeks to months.
Time-Sensitive
Starting treatment early improves the chances of full recovery.
Common Symptoms
- Sudden drooping on one side of the face
- Difficulty closing one eye
- Drooling or uneven smile
- Loss of taste on part of the tongue
- Increased sensitivity to sound on one side
What Increases Your Risk
A combination of medical, lifestyle and hereditary factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
1. Clinical examination
Facial weakness pattern helps distinguish Bell's palsy from stroke.
2. Rule out other causes
Assessment to exclude stroke or other nerve conditions.
3. Imaging, if needed
MRI may be used if the diagnosis is unclear or symptoms are unusual.
Treatment Approaches
Medical Care
- Corticosteroid Medication
- Eye Protection & Lubrication
- Facial Physiotherapy
- Regular Follow-up
Surgical Care
Surgery is rarely needed for Bell's palsy. In select long-standing cases with poor recovery, your specialist may discuss further options.
Treatment decisions are based on symptoms, imaging, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- You have mild, improving facial weakness

Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Facial weakness appears suddenly and worsens quickly
- Weakness affects your arm or leg as well as your face
