A head bump has been vaguely painful in general 7~10 days can be healed, the more serious injury may take a longer time. 1. General situation: the outer side of the head consists of hard skull bones and the top of the capitellum and other structures, with good protection, so most of the spontaneous head trauma is relatively minor, usually after trauma is soft tissue swelling, after ice, rest and other simple disposal, often about 7~10 days can be recovered, and will not be left sequelae. 2. Special case: if the patient is injured due to external force and the injury is relatively heavy, in addition to headache, accompanied by nausea, vomiting, dizziness and other manifestations, we need to be alert to the possibility of craniocerebral injuries, such as cerebral contusion, epidural hematoma, subdural hematoma, etc., and the recovery time of these cases need to be based on the severity of the contusion, the area of the hematoma, the location of the contusion and other factors to decide. It takes about 1~3 months for mild cases and may take 3~6 months or even longer for severe cases. If the patient’s headache symptoms are severe, or if the symptoms persist without improvement, he or she should go to the hospital promptly for treatment.
