I received a concussion week 3 and was knocked out, but came to in seconds. I finished the game even though I had a massive headache. I drive home after the game and had light sensitive for the following week. I played week 4, but didnt get to hard and still had headaches and another headache after the game. I played week 5 and was hit hard and knocked unconscious again. I played thay game out too. I sat week 6 after my er visit. Played wek 7 but no headache. Should i still be worried.
