maybe its cuz im crazy and decided to get not just my flu shot, but also my COVID and tdap booster...all at the same time....but i have been fighting a fever since a few hours after I got the shots, been having body aches and the chills like crazy, and the concoction has given me slight nausea and just bad shits man. not even the first versions of the vaccine did this to me. like im fighting demons and am having to take acetaminophen every few hours just to feel alive....
