Two months after the car accident, the patient is now experiencing vomiting.
Given the age, the likelihood of developing a chronic subdural hematoma is low, but it is still possible.
If there are accompanying symptoms such as persistent headaches, unsteady gait, or drowsiness, it is advisable to follow up at a neurosurgery outpatient clinic.

Post-concussion vomiting can be a concerning symptom, especially following a head injury. It’s important to understand the potential implications of vomiting after a concussion and what steps you should take to address this issue.

First and foremost, vomiting after a concussion can indicate increased intracranial pressure or other complications related to the head injury. While it’s not uncommon for individuals to experience nausea and vomiting after a concussion, persistent vomiting, especially if it occurs weeks after the injury, warrants immediate medical attention. The fact that you are vomiting clear, tasteless fluid could suggest that you are experiencing a buildup of cerebrospinal fluid or that your body is reacting to the concussion in a way that requires further evaluation.

Here are some steps you should consider:
1. Seek Medical Attention: Since you are experiencing vomiting two months after your head injury, it is crucial to consult a healthcare professional as soon as possible. They may perform a neurological examination and possibly imaging studies, such as a CT scan or MRI, to rule out any serious complications like a hematoma or other structural issues in the brain.

2. Monitor Symptoms: Keep track of any additional symptoms you may be experiencing. This includes headaches, dizziness, confusion, changes in vision, or any other unusual sensations. Documenting these symptoms can provide valuable information to your healthcare provider.

3. Stay Hydrated: While it may be difficult to keep fluids down, it’s important to try to stay hydrated. If you can’t keep water down, consider sipping on electrolyte solutions or clear broths. Avoid caffeinated beverages and alcohol, as these can exacerbate dehydration.

4. Rest: After a concussion, rest is essential for recovery. Ensure you are getting enough sleep and avoiding activities that require intense concentration or physical exertion. This includes limiting screen time and engaging in light activities that do not strain your body or mind.

5. Avoid Certain Foods: If you are able to eat, start with bland foods that are easy on the stomach, such as crackers, toast, or bananas. Avoid greasy, spicy, or heavy foods that may worsen nausea.

6. Follow-Up Care: If you have already seen a doctor for your concussion, make sure to follow up with them regarding your vomiting. They may want to adjust your treatment plan or refer you to a specialist, such as a neurologist, for further evaluation.

7. Emergency Signs: Be aware of emergency signs that require immediate medical attention. These include severe headaches, seizures, weakness or numbness in any part of the body, difficulty speaking, or any changes in consciousness. If you experience any of these symptoms, seek emergency care right away.

In summary, while vomiting can occur after a concussion, persistent vomiting weeks after the injury is a cause for concern and should be evaluated by a healthcare professional. Your health and safety are paramount, so do not hesitate to seek medical help to ensure that you receive the appropriate care and treatment.
