No mine didn't have spots either - could have been that picture - I have a better one in my file but that was the 1st one I found on the web - it came from Mass General based on the NEJM article that you posted dated about the 1st part of March.
I had never had it before either - it didn't scare me so much since it seemed to be so topical - I didn't have it with the 2nd Shingrix shot - just the 1st one. And I had absolutely NO reaction to the 1st Moderna - not even a sore arm. I was prepared for a down day or a couple of them - but nothing. I take the next one on April 06.
Mine reaction was pretty large and it worked its way down towards my elbow - started about 5 days after my 1st Shingrix shot then it got red, swollen, felt warm to touch - each day it got better and better - if not for the itching I actually felt nothing.
I used aloe and took some benadryl - yes, I have some allergies but mostly to airborne stuff like pollen - all upper respiratory not topical.
Yes, it was weird. You are wise to post about it here.
