CRAP! If it wasn't for bad luck, we'd have no luck at all!
I feel badly for you. I contracted chicken pox about 20 years ago after shaking the hand of a father of a friend who had shingles. Unknowingly of course until after the fact.
So having chicken pox as an adult was no picnic. So after getting CRPS, I opted to have the shingles vaccine a couple of years ago. Of course, the vaccine is no guarantee of not getting shingles, but if you get it, it is supposed to be a lighter case.
Is there anything we with CRPS don't worry about? Geezz....
Hope that your shingles clear up soon Littlepaw! And thanks to you for all of your insightful and compassionate replies here on this forum. They are very much appreciated!
