Patient's question:
Here is the English translation of the provided text, with the return characters kept as they are:", what should I do? My 3-year-old baby fell and hit his head on the same day he vomited and had a CT scan. The doctor said it was nothing and we came back. But he still vomited the next day, so we had another CT scan, which was also fine. After getting an injection, he stopped vomiting. In the morning of the third day, he vomited again. What should I do?"
Doctor's answer:
Based on the described situation, this may be related to a concussion, which refers to a temporary brain dysfunction that occurs immediately after the head is subjected to external force. The pathological changes are not significant, and the mechanism of occurrence is still a subject of debate. Clinical manifestations include transient loss of consciousness, retrograde amnesia, as well as symptoms such as headache, nausea, and vomiting. No positive findings are observed during neurological examinations. It is the mildest form of brain injury, and most cases can be cured with treatment. Generally, special treatment is not required; rest should be strengthened.
