Has your doctor mentioned Zovirax?
My son got shingles around one side of his trunk, after he got H1N1 (and pneumonia; it was the sick season). He got Zovirax and no pain meds (I just asked, after reading the posts). I know he had some pain because he was complaining to me, but once he sucked up the macho thing, actually went to the doctor, got diagnosed, and started taking the meds, apparently he was OK.
I'm scared to death. I had chicken pox and I hear that older people can get hellacious shingles. There's a vaccine, but I'm not old enough for it yet. I plan to be first inline the day that I'm eligible.
I'm sorry you're in so much pain,
