My 9yo DS has been having outbreaks of hives for about 9 months which the GP told us to treat with antihistamines. 3 weeks ago he had a severe outbreak of hives along with enormous swollen lips and wheezing (he is asthmatic). We took him to A&E where he had steroids and now we are waiting for an appointment with the specialist allergy clinic. He is taking antihistamines every day. This morning he woke up with mildly swollen lips and his eyes were maybe a little bit puffy. I think he has angiodema though neither the GP nor hospital doctor used this word. Can you have mild and severe angiodema? Should I take him to the doctor at every outbreak while I am waiting for the hospital appointment? I don't want to over-react nor be complacent and am worried about the best thing to do. We don't know what he is allergic to. Any advice?
