The difference between Bell’s Palsy and some of the other causes is really in the history of that particular problem. So for example, Bell’s palsy occurs out of the blue. It can be associated with the common cold. It can be associated with climatic changes. There are a number of reasons why the facial nerve might become inflamed and swollen, but it is a very quick process. The symptoms of Bell’s Palsy can be very similar to other causes of facial paralysis. So it’s very important to differentiate Bell’s Palsy from what else can cause facial paralysis. Some of those other causes can be quite severe and serious. Things like brain tumors or stroke. These have a very similar clinical appearance, but they’re treated in a much different way.
