I have small fiber PN and PMR. I received my first Shingrix vaccine Wednesday and have the second one scheduled for May 5th. The only side effect I had from the first shot was a sore arm on the arm where I received the vaccine. It didn't start until later in the evening and it's still tender if I touch the shoulder but not too bad. Hoping the second one goes as well. I have friends and family that have gotten Shingles and I really don't want to get it so it's worth any minor side effects for me.
