You should not push crayons up your nose because it can cause physical harm and potentially serious medical issues. Crayons are not meant to be inserted into the nose, and doing so can lead to a variety of problems such as irritation, inflammation, infection, and even blockages in the nasal passages.
If a crayon gets lodged in the nasal passage, it can be difficult to remove and may require medical attention. In some cases, surgery may be necessary to remove the object. Additionally, pushing objects into the nose can cause damage to the delicate tissues and blood vessels in the area.
It is important to keep small objects like crayons out of reach of young children and idiot adults to prevent accidental ingestion or insertion into the nose or ears. If you or someone you know has inserted an object into the nose, seek medical attention immediately to prevent further complications.
