Final answer:
A 'goose egg,' or swelling on the head, in a 16 year old can result from a bump or injury. It typically resolves within a few hours to several days depending on the severity, but medical attention should always be sought following a head injury to rule out more consequential conditions.
Step-by-step explanation:
The term 'goose egg' is often used to describe a swelling or bump on the head. Despite the catastrophic implications one might imagine, a 'goose egg' on a 16 year old's head most often results from a trauma or bump against a hard surface. The body's inflammatory response leads to the swelling at the site of the injury. The time it takes for a 'goose egg' to leave a '16 year old's head' will depend on the severity of the bump. Minor bumps usually resolve within a few hours to a couple of days. More significant injuries may result in swelling that persists for a week or more.
Regardless, it is always advisable to seek medical attention when a head injury occurs, to rule out more serious conditions such as a concussion or skull fracture.
