Bell's palsy is a type of facial paralysis that results in an inability to control the facial muscles on the affected side. Symptoms can vary from mild to severe. They may include muscle twitching, weakness, or total loss of the ability to move one or rarely both sides of the face.Other symptoms include drooping of the eyelid, a change in taste, pain around the ear, and increased sensitivity to sound. Typically symptoms come on over 48 hours
SYMPTOMS:The facial nerve controls a number of functions, such as blinking and closing the eyes, smiling, frowning, lacrimation, salivation, flaring nostrils and raising eyebrows. It also carries taste sensations from the anterior two-thirds of the tongue, via the chorda tympani nerve (a branch of the facial nerve). Because of this, people with Bell's palsy may present with loss of taste sensation in the anterior 2/3 of the tongue on the affected side

CAUSES:The cause of Bell's palsy is unknown. Risk factors include diabetes, a recent upper respiratory tract infection, and pregnancy.
Some viruses are thought to establish a persistent (or latent) infection without symptoms, e.g., the varicella-zoster virus and Epstein–Barr viruses, both of the herpes family. Reactivation of an existing (dormant) viral infection has been suggested as a cause of acute Bell's palsy. This new activation could be triggered by trauma, environmental factors, and metabolic or emotional disorders.Familial inheritance has been found in 4–14% of cases. There may also be an association with migraines.

What are recommended exercise for person with Bell’s palsy?
• Basic movement exercises such as the forehead wrinkle, eye closure, smiling, snarling and lip pucker at varying speeds and intensity for 10 to 15 minutes, 4 to 5 times a day.
• Lip closure exercises involving filling the cheeks with differing amounts of air, along with eating and drinking exercises while keeping the eye open.
• Expression exercises like to recreate common facial expressions, such as anger and astonishment.
