The head fell on the ground and dizziness appeared, which is related to brain function damage caused by trauma. First of all, we should pay attention to rest and observe the changes in the condition. If the dizziness and blurred vision gradually improve, there is usually no obvious harm, but if the headache and blurred vision do not improve significantly, and there is headache and vomiting, it is likely that an intracranial hematoma has occurred, and it is necessary to go to the hospital in time to do intracranial cranial CT examination. If a concussion or cerebral hemorrhage is found, hospitalization is required, and for severe cerebral hemorrhage, surgical craniotomy is required.
