Thank you for your question I am sorry that you are not feeling well In my opinion your symptoms sound consistent with a concussion A concussion is a brain bruise that can cause nausea, vomiting, lightheartedness, dizziness, foggy thinking, etc The best treatment is brain rest, meaning lots of sleep, no loud noises or sounds Symptoms usually last days but can go on for weeks to months If you have vomiting, are not acting correctly, then I would go to the ER to been seen because this can be signs of bleeding in your head If you don t have the above I would still followup with a doctor for followup Hope you feel better, Dr Dupy
