DD (12 months) had her vaccines yesterday afternoon and today has a very red, hot, swollen and sore leg (picture attached but doesn't show the redness well, it's very red in comparison to surrounding skin). She hasn't reacted to other vaccines and so I'm not sure if this is normal or not. She is walking with a limp and is very conscious of her leg.
Can someone reassure me that I'm being PFB and this is normal?
