I barely felt it but the next day my arm was very sore and it stayed that way for a couple days but not a big deal :)
I just got it two days ago it didn't hurt at all while getting it but yesterday my arm was so sore ..
it hurt me! when I got it I winced and the nurse was like "oh my god, if you can't take a shot how are you suppose to give birth" like I'm sorry, I don't like shots lol
My arm was sore for like 2 days after I couldn't sleep on it
