So I fell down the end of my stairs and hit my head really hard on something at the bottom. I went to the doctor and was diagnosed with a possible mild concussion and they did a CT. Scan came back clear, but I keep hearing stories of bleeds happening a few days after injury. I guess I’m just worried cause I hit it SO hard and it still hurts. I’m not dizzy or nauseous, but I have struggled to stay awake this afternoon. Should I be concerned?
