my arm has hurt much less than the first dose, which i thought was a bit unusual. the injection site actually hurts now rather than my entire arm. around 12 hours after i got the 2nd dose, my lymph nodes in my neck started to swell and i got a pretty rough headache. i woke again at 5am with a slight fever. it's a couple of hours later and my headache is coming back, the injection site is pretty sore, i still have a bit of a fever (afraid it might get a bit worse in the coming hours), swollen lymph nodes (this one is pretty rough. i can hardly move my neck because it's so tender), and i'm very lethargic.
