My DS is 4 and has CMP and egg allergies. In the past his reaction has been immediate vomiting and hives. However, today a milk carton was accidentally dropped near him in the supermarket. A very small amount splashed onto his cheek. His face and eye swelled up and he was complaining that his tongue felt funny. We immediately gave him Piriton - the reaction took about an hour to subside and his eye was still swollen several hours later. Given that this was a contact reaction and none was ingested do you think we should be given an epi pen? I keep thinking "what if it had splashed onto his tongue?". I was hoping he might grow out of it soon but today was quite severe. Any experience or advice would be appreciated. I have booked a drs appointment for tomorrow but wanted to see what if anyone has had a similar experience. It was quite frightening.
