My fiancé was just jumped by 4 men walking home from the store. I cannot get the exact details from him because his speech is slurred and he seems confused, also has trouble keeping his eyes open and staying awake. His pupils are tiny, and nothing else seems to be injured. But he just had a fasiotiomy about three weeks ago on his left calf area. He is in major pain there, and has the beginning of a black eye. He does not want to call the police because only his favorite hat, his phone, and $5 (all he had on him). But I think we should.. Anyway, he is starting to doze off despite my best efforts to keep him awake, and he seems to be getting more confused. He is slurring his words very badly and saying things that do not make sense. I worry about a concussion, even though he says he didn't fall, or hit his head on the sidewalk.. He was punched in the face (eye area) twice. Should I get him to an emergency room?
