hello, My son is 5 years old. He fell from the school playground last Friday . Saturday morning, I noticed both his eyes have a black brownish ring under the eyes. left is worse than right. saturday afternoon, he starts to have swollen eyes and headache and leg pain. Sunday morning his eyes seem a little better. yesterday night he suddenly has some allergy-like symptoms. coughing and liquid sound when he breath, it developed very quick, reach the peak in 10 min and then starts calm down. this morning, no these symptoms. but a headache and eye puff. should I take him to see a doctor?
