The exact cause of Bell's Palsy is unknown, as of 2015, but stress may contribute to the development of the condition, according to Tracee Cornforth for About.com. Other less likely causes of Bell's Palsy include hypertension, diabetes, toxins and infections. It is also possible that Bell's Palsy is genetic.
Steroids are often the most common treatment for Bell's Palsy, but the effectiveness of these drugs is still up for debate, explains Cornforth. Many people also try to use eye drops to treat Bell's Palsy, as dryness in the eyes accompanies the paralysis of the face. Relieving stress can also help to ease the effects of Bell's Palsy, so relaxation exercises often help. Most people who have symptoms of Bell's Palsy can improve up to about 80 percent after a few weeks, though recovery may take a few months, and for some patients, recovery never happens, even with treatment.
One way that people often treat Bell's Palsy is to practice facial exercises and massage, states Cornforth. This can also help to prevent the recurrence of the condition. Patients do these exercises and massages several times a day in front of a mirror by making faces, even if there is no noticeable facial movements. People can also massage the facial muscles with the hands to speed recovery of Bell's Palsy.
