Question: Hi, I received the second pneumococcal vaccine shot this past Thursday and didn't expect or notice anything healthwise. Yesterday I had some pain in the left shoulder where I received the shot and I noticed some pain and swelling in what my wife (30 years ago she was an RN) and I deduced as my adenoids. I have a severe case of cervical stenosis and shoulder pain is not unusual. My wife said her adenoids swell occasionally so I buried the pain in my mind. This afternoon I started having pain in my left armpit which was a more burning type of pain. Tonight the pain is going up the left side of my neck on the outside and I inspected the area in the mirror. I now have rash spreading from my neck, behind my ear and proceeding down the top and front of my chest. I got a little concerned at that point and remembered receiving the shots (I also received the flu vaccine). Should I go to an emergency room? I don't feel sick per se.
