Hi there:
I did have the shot about six years ago and about eight months ago I did get the shingles, however, it was a very mild case, thank the Lord. They lasted about two months. I had them mainly on my right arm so I was very lucky, not to much pain. I am guessing that the shot minimized the degree of them for me.
Good luck to you and I hope you get some relief real soon.
Take care.
