I woke last night at 2am with a fever. My arm is tender, and swollen a bit at the injection site. the site is pinkish. I feel like someone punched me really hard in the arm. It didnt hurt for the first couple of days, but now I am questioning why I did this. I will call the MD and ask if this is normal.

Does anyone else get swelling in the shot area? pink? its not painful, but its quite sore.
