<human>: I was talking to my son in TN today and we were discussing allegies. He has had about 3 episodes of breaking out in a rash but first he has a burning sensation in his ears then gets dizzy and feels like he will pass out. one time it happened while in line at a convenience store another time in a restaurant. He stated that he had not had any thing unusual to eat before his occurence. Any info would be appreciated.
<bot>: Hi, Perhaps he had hives. Hives are itchy welts with surrounding flare. There can be associated dizziness and feeling of passing out in a severe reaction. Hives can happen as an allergic reaction to either food or food preservatives, Chat Doctor.  I suggest him to take an oral antihistamine e.g. Tab Cetirizine once a day for a few days. Topically he may use a soothing lotion e.g. calamine lotion to calm down the rashes. Hope I have answered your query. Let me know if I can assist you further.
