Its not an allergic reaction. Remember that shot also has tetanus in it. It's normal for it to be red and sore and that lump can actually last a couple weeks.
Yep, both my husband and I had that too. It went away after a couple of days.
I got mine done yesterday aswel and my arm really hurts still but there's no appearance or itchiness it just really hurts n too think my lil man is going to get this at 6 weeks old
Ahh I got mine yesterday and it still hurts to move my arm!
Mine aint that soree no more just like a red circle around mine itches still has a lump
