Hi there, thanks for asking. Fortunately, in more than 90 percent of the cases the palsy
reverses completely, although it take more than 6 months to be fully observed. Using a steriod
facilitates the healing in the first few weeks, as you took and there is no other medication or supplement to be used to facilitate the healing process. having a healthy diet would be sufficient. As you mentioned, avoiding stress
and also learning some ways to cope with stressful situation could help for prevention because stress has been known to be one of the factors responsible for the Bells Palsy. Some people take it after viral infections like mononucleosis
or some people following tuberculosis
. So having a good hygiene will help significantly as well. I wish you a good health!
