For at least the next six - eight weeks, ELIMINATE SUGAR from your diet. When I had shingles a few years ago, getting off sugar helped because shingles seem to thrive on sugar.
Take supplements to strengthen your immune system. As your body strengthens, the pain will get less and usually the lesions will go away within 6 months or so.
HOPE YOU FEEL BETTER... THIS IS A MISERABLE CONDITION!! :-)
