Received the shingles vaccine one week ago and yesterday I noticed a red rash, itching, swelling, warm and some paid. Mostly itching and the rash is square shaped, 5x5), on the back of my arm beginning at the top of my elbow going up the back of my arm. I was also working in my garden yesterday and am concerned about tic bites. Is it normal for the symptoms to show up a week after the injection?
