DS (4.3) had pre-school booster of DTP-IV yesterday
I know they say to expect a little swelling around the site and understood that to mean about the size of 50p piece around where the needle went in
but the whole of DS's upper arm is pink (not red) and looks twice the size of the other arm
should I be worried .. or is this normal? is there anything I can do to help .. he isn't complaining much but says it hurts a little
