<s>[INST] My 4 year old grandson was outside playing this afternoon and he developed some mosquito like bites on his face, arms, legs, neck and feet. They proceeded to get bigger where they became one big welp and went away. Well he s asleep now but be for he went to sleep they havecone back ? We put cortezon cream what can or should we do? Is it ok to let him sleep? Please help concerned grandmother! [/INST] Thanks for the query.Better to diagnose if i can see the pic.As from your description it looks like allergic rash, mostly urticaria or insect bite reaction.Try syp. cetrizine after consulting a doctor.Dermocalm or some calamine lotion can also be used for local application.Hope i helped you. </s>
