Hi I'm Taylor im 17 I currently have a concussion from a field hockey game last Thursday me and another girl hit head on and I had lost my vison for a couple minutes. I hd passwd the concussin test except the vison part. On Sunday morning my parents found me unresponsive and called 911 in the emergency room my blood work came back okay and along with my CAT scan. I am really worried because I am currently experiencing dizziness, nausea, and feel as if I am going to pass out. I am not sure what exactly is going on because I have been symptom free from concussion headaches and light sensitivity for the past 48 hours. If you could please let me know as to what may be going on that would be great. I am on Lamictal 150mg and taking a natural supplement called NAC. Not sure if its a med related issue or what but I am very worried.
