I didn't get the shingles vaccine (I'm on PD). Actually, I'm not sure I was offered that option. But my wife got shingles about 3 months ago. Her worst symptoms lasted about a month and she had severe pain. Then about a month after that I started breaking out with bumps (not regular pimples) and had itching that almost drove me insane. It was almost impossible to sleep and I was miserable.
I'm convinced that I had chicken pox. My neph kind of brushed it off and blamed the itching on elevated calcium and phosphorus levels. Now the labs were above normal but not that much higher than always. I wanted to have them test for chicken pox, but that would have meant a referral to an ID specialist and well, no, we'll just wait and see how it progresses...
Whether it was chicken pox or shingles it's something neither my wife nor I want to go through again! Thankfully, I can now sleep through the night and the itching has mostly gone away.
