Thanks for writing to health care magic.
Bells palsy involves facial nerve
This nerve plays an important role in our facial activities like eating ,drinking etc and facial expressions.
Treatment invovles steroids
and nerve rejuvinators.
Vitamin b6 or pyridoxine
is one of the best rejuvinator ever known.So You can definately continue with Renerve injections.
I hope this can solve your problem.Take care.
