The most common issues after concussions are headaches, inability to focus, fatigue and drowsiness, dizziness, visual problems, emotional disturbance, and sleep disturbance. Therefore, all your symptoms are normal. Since you lost consciousness, you should have a CT or MRI scan of your head. In addition, you have begin to vomit persistently or have worsening of your symptoms, you should also have a CT/MRI scan. There is no specific treatment.
