I realize your post was from back in 2019. Wondering how your symptoms are now. I got a Shingrix vaccine, with the 2nd dose in Feb 2021 and have had similar symptoms to what you describe and more: burning, tingling, prickly, scratchy sensations in back, near elbows, above needs, calves, feet for 5 months now. Had thoracic MRI done - normal. Blood work for all kinds of things all came back normal. Getting an EMG done here soon. I took an antiviral med for 3 weeks (probably about 5 months too late) and now Gabapentin for the past month. All regular clothes feel like sandpaper on my back so the only clothes I can wear are anything made out of nylon. Can't sleep on cotton sheets, too scratchy. At least I can wear some clothes. Like you, hoping this doesn't last for life. There can be worse things, but aggravating when you try to do something good for your health and it turns out bad. If I would have known what negative things Shingrix could do, I would never have gotten the vaccine. Not all vaccines are good for people and anything we do, whether we get it or not, has risks. I have good days and bad days.
