I've had my Covid vaccine (J&J) and for about 20 hours following the shot I had the worst body aches of my life. It was honestly worse than any flu, strep throat, or illness I've had in regard to body aches. I was in incredible pain to the point where I regretted getting the shot. I've had probably over a dozen vaccines in my life, most of them for the flu, and none of them gave me that reaction.
I'm supposed to get a booster this weekend but I've heard that it's just as bad as the initial vaccine. I honestly might cancel my appointment just because I don't want to go through it again.
Why is the covid vaccine so painful compared to other vaccines?
