text: ive had   crohns for 24yrs;no  meds for the  past 18yrs,had shingles  for  a  wk  now;could crohns? contributed to my  having  shingles? umm possibly, crohns does have an immune origin of some sort so it is possible that the crohn's could have triggered it somehow, were you having a flare before it started, otherwise you may just have gotten it normally
