What Happens in Bell's Palsy?

Bell's palsy occurs when the facial nerve, which controls your facial muscles, becomes inflamed or swollen. This swelling squeezes the nerve as it passes through a narrow bone canal, leading to weakness or paralysis. Imagine a garden hose getting kinked - that's similar to what happens to your facial nerve in Bell's palsy.

Signs and Symptoms

The main symptom is sudden weakness on one side of the face. You might have trouble closing your eye, smiling, or raising your eyebrow on the affected side. Some people also experience pain around the ear, changes in taste, or sensitivity to sound. These symptoms usually appear quickly, often overnight.
Bell's palsy is characterized by a sudden weakness or paralysis of the facial muscles, typically affecting one side of the face. It is the most common cause of facial paralysis, and its exact cause remains unknown.

Who's at Risk?

Bell's palsy can affect anyone, but it's more common in adults between 15 and 60 years old. Pregnant women, especially in their third trimester, and people with diabetes or upper respiratory infections may have a higher risk. However, having these risk factors doesn't mean you'll definitely get Bell's palsy.

FAQs

Can Bell's palsy affect both sides of the face?
