Diagnose: Bell's Palsy
Bell’s palsy is a condition that causes temporary facial paralysis (palsy). It usually only affects the muscles on one side of your face. You may have a lopsided smile or an eyelid that you can’t fully close. It rarely affects both sides of your face.

Treatment:
Most cases of Bell’s palsy improve without treatment. Still dr may recommend one or more of these therapies for symptom relief and faster recovery:
Eye care: Eye drops, including artificial tears, soothe dry, irritated eyes. If eyelid won’t close, may need to wear an eye patch to protect that eye from drying, irritants and injuries. Eye care is very important to prevent damage to cornea, a serious complication of Bell’s palsy.
Oral corticosteroids: Oral corticosteroids (like prednisone) can help decrease nerve swelling. This treatment is most effective when start it within 48 hours of noticing symptoms.
Antiviral medications: Antiviral medications may speed up recovery. But it’s unclear how much benefit they provide. Providers typically only prescribe them for severe Bell’s palsy. This treatment works best when you combine it with oral corticosteroids.
Electrical stimulation: Although some dr recommend electrical stimulation to prevent facial muscle loss after Bell’s palsy, studies haven’t shown any benefit of this treatment.
In the rare case that Bell’s palsy doesn’t go away, functional facial plastic surgery procedures are an option. They can help correct facial asymmetry and assist with eyelid closure.
