My dad had shingles 3 years ago - it was so severe that he was in hospital 43 days...he was left with severe pain in his foot...debilitating pain.... he has tried LITERALLY everything for postn.shingles pain- tens, creams, nerve stim, opiates, lryica, neurotin. He got the shingles shot so he wouldn't get it again...but he just got out of the hospital with shingles again - this time it attacked his good side..What can we do? do you think this is autoimmune problems? how can you get it again???? and how can doctors be so cruel to say nothing can take away the pain??
