When dizziness and vomiting occur after a blow to the head, it is recommended to go to the hospital for a detailed head examination in a timely manner. If a CT of the head is done, if it is caused by concussion, attention should be paid to more rest and avoid further activities, and then physical methods such as hot compresses or massage of the head and acupuncture should be used to relieve the symptoms, which can also be treated with oral flunarizine capsules, nimodipine and compound brain protein hydrolysate tablets. Most patients are able to relieve the symptoms of this disease within a week or so, but it is also important to eat a light diet with less oily and spicy food during the treatment period. In addition, dizziness and vomiting can occur if the head is hit and the skull or brain tissue is directly damaged, and this type of illness should be treated promptly by a doctor. Some patients may also suffer from dizziness and vomiting caused by pressure on pain-sensitive structures in the skull and irritation after being hit on the head, and they should seek medical attention for such injuries to avoid serious consequences of brain damage.
