i fell and hit my head an a wall on sunday. I went to the hospital on monday due to the amount of swelling /pain/feeling sick and light headedness. They told me i had a concussion and burst blood vesselsand a CT scan wasnt needed now 3 days later, i still have really bad headaches, bruising, swelling, feeling light headed, nausea, feeling tired all the time and sensitive to light. Is this normal?
