Small moveable lump on left collarbone
I had shingles vaccination several days ago and had pain and redness around the area of injection. My underarm has been sore and uncomfortable, but not really painful. The redness has gone away, but this morning I've noticed a small lump on my collarbone on the side where the injection was given. My underarm is still sore. Is this related to having the shingles vaccine or should I go to my doctor in case something else in going on?
