Hi I was drinking a coffee with my sister when my skin suddenly got really itchy then I got these bumps, they turned into blisters soon after, went to out of hours docs who said unusual but prob milk, avoided milk. A few hours later I got hives, they said biphasic reaction. So no milk and now I've had so much hives tonight, why is it?? Annoying me not knowing. I'll attach pics from first reactiom the tonight's
