The main causes of children hitting their heads frequently include the following: First, the symptoms caused by children suffering from sinusitis. If children have sinusitis, it will cause unrefreshing head and a feeling of swelling and fullness in the head, and at this time children will involuntarily hit their heads. In this case, children will have symptoms such as nasal congestion and yellow pus nasal discharge, and they need to be given antibacterial medications to treat bacterial infections and control sinusitis. Secondly, symptoms caused by otitis media in children are seen in younger children. Children’s ears will hurt after otitis media, but the child is too young to locate it accurately, so he or she will have a headache and needs to be taken to an otolaryngologist for an otoscopy.
