What Is Bell’s Palsy?
Bell’s Palsy, also called idiopathic facial paralysis, is a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. The disorder is fairly rare, with fewer than 200,000 US cases reported each year. It is important to note that, while it is not related to stroke, it is the most common cause of facial paralysis. The condition most often comes on very suddenly but does improve on its own within a few weeks. Although it is not clear as to the actual cause of Bell’s Palsy, it is thought that the cause in some cases might be the herpes virus that also causes cold sores.
