Basic wellness methods may help prevent Bell's palsy. This is because the common cold sore virus is often involved. A healthy diet, adequate exercise, and stress management are all important.
The prognosis for Bell's palsy is good. With or without treatment, most people begin to feel better within 2 weeks. About 80% recover completely within 3 months. In a few people, symptoms may last longer or even fail to disappear completely. Bell's palsy affects only one side of the face at a time. It is possible, though not usual, for Bell's palsy to occur again in the same person. Experts do not agree on the rate of recurrence, but at most it is only 10 to 15%.
Bell's palsy is not contagious. People who have it can return to work and their usual activities as soon as they feel ready.
