###Human: Why is there continuous sneezing in a child? ###Assistant: Hi. I have gone through the query you posted. According to the history you have given, it is an allergy because of the paint smell. That is the reason he is getting sneezing and running nose. As you think, it is not because of some foreign body in the nose or in the throat. If the foreign body is in the throat, symptoms will be like a continuous cough, breathlessness. If the foreign body is in the nose, they will have a bad smell from nose and bleeding can happen with mucus secretions. So no need of any X-ray or investigations for the child. Differentiating between allergy and viral infection, you have to do some blood test and always viral infection will be associated with fever. So nothing major to worry. What is the weight of the child?
