Every COVID shot that Moderna had come up with he had taken, and this was the first time he noticed these welts right by the elbow, on the underside of the arm, did not itch or hurt. He describes them as swelling/welts. The next day, they were gone. He also added that he put some hydrocortisone cream on it because he did not associate them with the shot, but then he was reading it could cause something like this. it was a painful arm afterwards, but for the first time he experienced chills, low grade fever, muscle aches. He did had back problems, but that it hurt ten times worse and then the welts, but within a day or two they were all gone. It was by accident that he noticed the welts. He was shaving and was wondering what that was at the bottom of his elbow. He thought maybe it was a mosquito bite and put the hydrocortisone on. he reiterated it was gone the next day. Pain at injection site, fatigue, headache, muscle pain, joint pain, chills, axillary swelling or tenderness, nausea or vomiting, agreed that he has experienced all of these except the nausea and vomiting.
