Question

A 4-year-old boy accidentally hit his left forehead on the wall tonight, and a pouch about the size of an egg yolk formed. Should we go to the hospital, and how long does it generally take for it to heal?

Answer

Based on the description provided, if there are no abnormal symptoms such as dizziness, there is no need to go to the hospital for a detailed examination and treatment. Generally, you can treat it symptomatically with oral cephalexin tablets and apply local cold compress therapy. I hope my explanation is helpful!
