Answer:
she is bleeding
Step-by-step explanation:
an allergic reaction wouldn't hurt it would itch, but it depends on where the reaction has formed. but it says that she was scratching the area of concern making it bleed so yes that would hurt. Benadryl would be a good idea to get the reaction to calm down but you need to stop the girl from scratching the area otherwise it will get worse i dont know if im right, im very sorry if its wrong
