I am 69 years old and this past Friday, June 30, 2017, I received the Shingles shot under my right arm at Walgreen s as my insurance covered the expense. However, I did not get any side affects as I came home to rest according to the doctor. Yesterday, I noticed that I gotten a redness on the spot where my shot had been given and a little itching with a little pain. This morning, I have noticed that the redness has spread a little more and I am trying not to scratch and I can feel like a small bump. I am wondering is this after affects? I am doing my normal things and try not to think about this and can you provide some input?
