My 4 Yr Old Son Took The Flu Shot On
My 4 yr old son took the flu shot on Saturday morning. By Sunday morning he had a bruise approximately 3 inches by 4 inches on his right upper arm. The area is reddish-purple and is very hard, a tad warm but not hot. It has what looks to be tiny blisters in the area. He complains at the slightest touch. Is this normal?
