Bell's palsy is a type of facial paralysis that affects one side of the face. It occurs when the facial nerve, which controls the muscles on one side of the face, becomes inflamed or damaged, resulting in weakness or paralysis of the affected side. The exact cause of Bell's palsy is not known, but it's believed to be related to a viral infection.
Symptoms of Bell's palsy can include drooping of the mouth, inability to close one eye, drooping of the eyelid, and difficulty with facial expressions. Most people with Bell's palsy recover within three to six months, although some may experience long-term effects.
Treatment for Bell's palsy typically involves medications to reduce inflammation and improve nerve function, as well as physical therapy to prevent muscle atrophy and improve facial movement. In some cases, surgery may be necessary to correct any lingering facial asymmetry.
If you think you may have Bell's palsy, it's important to seek medical attention right away. While the condition can be frightening, most people with Bell's palsy make a full recovery with proper treatment and care.
