My 9 year old daughter came home with a swollen lip that went down a few hours after taking Benadryl. It happened again a week later. We tried I figure it out and go over foods she ate and came to no conclusion. It happened a third time but this time she got hives on her thighs and arms and even gets swollen fingers and toes. We went to an allergist who did food testing and seasonal allergy testing as well. I'm waiting for answers but until then if anyone has had similar incidents please any help can help. Thank you.
