My sister has had bells palsy for 3 months now...with each passing day she is becoming more frustrated...was on predisone and antiviral med at the beginning...she does facial nerve exercises and tapes her face at bedtime..just want to know why do some people recover in a few weeks or a month and others it takes longer...they say it is from a virus?  How long can this go on for??? Will acupunture speed things along??? I feel so bad for her...she doesn't want to go out b/c people always ask her what happened....very upsetting....
