I didn't have a good experience in the emergency room either. They missed my diagnosis all together as well. Told me it was in my head. NOT...a year later after multipal complaints I got the proper tests. It was not in my head at all. Moral of story, I don't think emergency rooms can detect everything. I think they rule out the most serioius of conditions, and send you off. They ruled out stroke, which I suppose was the worry they had. I am sorry your husband got the painful shingles. I got my shot this year in hopes that I won't get it. I wish you all the best. ginnie
