Bell’s Palsy 100% cured by Acupuncture Bells Palsy is a neurological condition where the facial muscles become weak and paralysed due to trauma to the 7th cranial nerve. This nerve provides sensation and movement to the whole side of your face and even part of your tongue. When this nerve becomes inflamed, it stops sending signals to the facial muscles and becomes paralysed. In western medicine the cause is unknown, and they say it is non permanent, resolving itself in several months. The problem without seeking treatment, is you are prone to developing it again, and possibly more severely.
