Thank you for using Ask a Doctor service. I have gone through your query and here is my advice. You seem to have Hives. Hives present as itchy welts and redness/ flare. Allergic reaction to a food or food preservatives is a common cause of Hives. Other causes include infection, Chat Doctor.  I suggest you to take an oral antihistamine e.g. Tab cetirizine 10 mg once a day for a few days. In addition, I suggest you to apply a soothing lotion e.g. calamine lotion to help reduce itching and flare. Hope I have answered your Quertle me know if you need any further assistance. </s>
