Just a little tidbit of info about shingles...I got them last may on my scalp. I had them for about 4 weeks before I figured it was something bizarre (i thought it was an 'old person' thing too)...anyways, they wouldn't give me anything for it as I'd apparently "had it too long for antivirals to do any good"

Whatever...he said it should be gone within 3 months and that I'd never get them again. The initial breakout on the left side of my head took about 6-7 months to go away, and then I got a new outbreak on the other side of my head and I've been getting a few places ever since...HA What do doctors know?
My grandmother has had them at least half a dozen times.

Mom said that having them actually makes you more prone to getting them again...of course, mom has no medical degree, but she seems to be more correct than the dumb doctors.
Also, as far as contracting chickenpox from someone with shingles, it's not as easy as it sounds, apparently. The person who hasn't had chickenpox (or the vaccine) must actually come into contact with the sores in order to catch it...it's not very airborne.
