Sometimes kids put something in their nose and don't even tell it to parents etc. It is always advisable to visit ENT specialist earliest if child tells about same. Discharge from one side of the nose can be a clue to same. A kid inserted crayon a month ago and even told same to parent but missed on parent's initial examination and taken lightly. Now they came to me for nasal pain and discharge. On endoscopic examination one side nasal cavity discharge was clue to suction clean. Impacted Foreign body visualised and removed under endoscopic guidance. Batteries, wooden objects and insects etc can be threatening to nose structure. Never attempt self removal as can slip backwards and into windpipe which can be life threatening.
