<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have an mind brain trama 5 days ago, Today, I accidentally miss my pillow my head fall onto the bed. I feel unbalance very dizzy. I also feel an burning sensation on the back of my head . Do I need to worry ? Ps: I went to ER on my first brain trama CT scan show fine,  <response>: Hello, If these are newer symptoms that youre described compared to 5 days ago then, it might be wise to check in with your doctor to ask them what they think about getting another CT of the head just to be sure something hasnt cropped. But from youre describing I dont sense that theres anything to worry about at this point. 5 days after a head trauma causing mild TRAUMATIC BRAIN INJURY is not that much time, so I wouldnt worry too much about not feeling all back to normal just yet. But if you develop serious symptoms such as sudden onset nausea, vomiting, or difficulty staying awake or alert to your surroundings then, I would definitely suggest a visit immediately to an ER. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
