Our Primary doctor said that you could get shingles again (and maybe worse) if you didn t take the meds 3x s a day, and just one made my husband very ill with terrible stomach ache. He s doing well with out the meds, ($90.00 out the window). It sounds like to me a scare tactic by an uninformed primary doctor that he s not never going back to! Our Gd-daughter is becoming a DO, smart as a whip and more into natural care, yea!
