One of the most important things to do is seek medical treatment immediately. Don’t just assume that your headache, dizziness, and vomiting will go away on their own. Those could be signs and symptoms of a more serious TBI condition.
The sooner you see a doctor and get x-rays, MRIs, and CT scans, the sooner a doctor can treat you. Only then can you be safely on the road to recovery.
Immediately seeing a medical doctor also demonstrates the importance of your injuries and that they are actually real and potentially serious.
It also helps your case if you continue to follow up with your doctor and follow through on the prescribed treatment, including taking medicines, going to all rehabilitation appointments, and getting all diagnostic tests.
