So I got two shots of Pfizer to begin with, my last shot being at the end of March. I’m a 25 year old woman who is def considered obese. I got a Moderna booster on Friday around 3pm. My arm hurt so bad I couldn’t sleep after like 3am Friday night. The next day I just felt kind of weird, couldn’t really manage my temperature comfortably, so I took my temperature and had a 101 fever. My body temp is usually 96.5 or so so this was substantial for me. Couldn’t really sleep that night either because I was freezing all night long. I had a fever until last night (Sunday). I also developed a really stiff neck, achy armpit and substantial headache around midafternoon yesterday. But I did sleep through the night! It’s now Monday night and my neck and head hurt way worse. It’s spanning from the base of my neck, up into the back of my head and through to my forehead. I love vaccines, I’m a student of public health, but omg I’m getting my ass kicked right now lol. I didn’t have any side effects beyond a sore arm from Pfizer so I’m just a little… idk, impressed? By this intense immune response.
