Bell’s palsy is a condition that causes sudden weakness or paralysis of the muscles on one side of the face. It happens when the facial nerve (7th cranial nerve) becomes inflamed or compressed.
🔹 Common Signs & Symptoms
You may notice:
- One side of the face droops
- Difficulty closing one eye
- Drooling from one side of the mouth
- Trouble smiling or making facial expressions
- Loss of taste on part of the tongue
- Ear pain on the affected side
- Sensitivity to sound
🔹 What Causes It?
The exact cause isn’t always known, but it’s often linked to viral infections, such as:
- Herpes simplex (cold sore virus)
- Flu or other respiratory viruses
These viruses can cause swelling of the facial nerve.
🔹 Is It Serious?
It can look scary, but the good news is:
✅ Most people recover completely within a few weeks to months
✅ Early treatment improves recovery
🔹 Treatment
Doctors may recommend:
- Steroid medicines to reduce nerve swelling
- Eye protection (artificial tears, eye patch)

🔹 When to See a Doctor
👉 If someone suddenly develops facial weakness, they should seek medical help immediately to rule out a stroke and start proper treatment.
