No pain during the night and Shingles seem a little better today!
I think Merck makes a successful Shingles drug
Actually it's a Chicken Pox vaccine. As it is the same Varicella Zoster virus, getting a booster of the vaccine helps reduce the occurrence of Shingles considerably. Once you get an episode of Shingles, the vaccine is no good for that. The reason you get Shingles even after you've had Chicken Pox is that it's a Herpes virus, and we all know Herpes is forever!
Let it be known there are a lot of variants of the herpes virus and the Shingles and Chicken Pox are not the Pecker Version!
No one is speculating how you got it.... 
Just stating the facts did not mention anything about myself.
Plenty of versions of herpes virus affecting people, including Type 1 (above the waist), Type 2 (below the waist) [unless....

] , Varicella Zoster or Chicken Pox (type 3), Epstein Barr primary mononucleosis, cytomegalovirus (CMV) and a couple of other rarer one.
