[|Human|] Hi, My son is severely food allergic and had a bakery biscuit 2 days back. He vomitted and was wheezing, so we gave him 1 ml of benadryl and he was doing fine. Today we notice his inner lips and inside of cheeks to be black. Is it something to worry. What do you want me to do. thanks, Mani
[|AI|]  Hello, Welcome to Chat Doctor, Food allergy is an immune system reaction that occurs soon after eating a certain food. Even a tiny amount of the allergy-causing food can trigger signs and symptoms. The most common food allergy signs and symptoms include Tingling or itching in the mouth, Hives, itching or eczema, Swelling of the lips, face, tongue and throat or other parts of the body, Wheezing, nasal congestion or trouble breathing. In some people, a food allergy can trigger a severe allergic reaction called anaphylaxis. This can cause life-threatening signs and symptoms. There are skin tests and blood tests to detect the foods that your son may be allergic to. A specialist in allergy will be able to arrange that. Thank you.
