What causes facial numbness in children?

Possible causes of facial numbness in children include prolonged低头 (looking down) while using mobile phones or studying, which may lead to cervical disc herniation and compression of facial nerves. Facial neuritis could also be a factor, possibly related to local trauma or cold exposure. Additionally, conditions such as influenza, frontal sinusitis, and gout may contribute—when children suffer from these illnesses, they often experience persistent pain in areas of the face supplied by the trigeminal nerve, along with electric shock-like pains that cause facial numbness. Other factors include exposure to cold wind after sweating, frequently washing the face or hair with cold water—leading to facial chilling—as well as heavy metal poisoning or drug toxicity, which might also trigger facial numbness. It is recommended that children experiencing facial numbness seek prompt medical attention at a hospital to avoid delays in diagnosis and treatment.
