Should i take my son to the er? he has a bee sting with a ugly, swollen red rash about 10-11 inches long. he's breathing fine.

Benedryl: The nasty reactions(breathing pbs) to a bee sting will be evident within 15-20 min if they require er care. Swollen extremities or hives can often be minimized by giving Diphenhydramine (benedryl) in proper doses every 4-6 hrs. If the kid has major sx like abdominal pain & lethargy with the event, a workup by an allergist may be worthwhile soon as rxns can worsen in the future.
