I am 17 and at cheer practice a girl fell out of her stunt and onto me. her elbow dug straight into my eye socket and then hit my nose severely hard. I couldn't open my left eye for ten minutes and my nose was hurting bad. after practice was over nothing felt better. the left side of my face went numb and I had a horrible headache. my friend took me to the hospital. they did a CT scan and said I had no fractures but severe orbital bruising. this is the day after and my left eye feels crossed and I have a horrible headache. it's has been swollen since the incident. it's not near as bad, but it's still very visible. I've had a concussion before but I don't k oe if I should go back. what could be the problem?
