hi, first Bells Palsy is not the same as a stroke. it is a infection typically viral such as Herpes and before u run off, 70% of the population have some form of Herpes Simplex
so have u had herpes
have u ever been prescribed Acyclovir or Valtrex and if so TAKE SOME MORE FOR A WHILE
as for stroke; do u take aspirin and if not then take one every day, if it upsets tummy get the kind that r coated to dissolve in the intestinal tract
THE TROUBLE with balance does not seem correlated to your other symptoms and seems to be an inner ear thing
DO U know what ear candles r and how to use. if not call around to health food stores to find them and ask how to use when u purchase.
HOPE THIS HELPS
