Hello! I understand your concern! The answer is yes. In my opinion you have had a mild brain concussion . The reverberatorion inside your head , the odd feeling , dizziness and headache are typical symptoms of brain concussion. It doesn t matter that you didn t lose conscience after the fall. It doesn t happen all the time. If you were my patient I would recommend a little rest. I would like to know if you are taking any therapy for other reasons like antiagregants or anticoagulants. These drugs can cause intracranial hemorrhage after concussion. I suggest that if you are not feeling well after some days, or you feel any body weakness you should go to the doctor and have a CT scan to rule out hemorrhage. If every thing goes better in the next day, it means nothing serious has happened. Hope to have been helpful! Best wishes Dr Abaz Quka
