My daughter thinks she may have been bitten by a black ant on the playground at school yesterday afternoon. She didn't feel it but did knock one off her are. By this afternoon she has two large swollen bumps on her arm. No big variance in color but you can see the bumps, which are a swollen light flesh color, surge red, with blood I guess, as her heart beats. What should be out course of action? I've never seen a reaction to an ant bite.
