hi doctor, my concern is about my son. I just experience a event where He was complaining of headache and his temperature drop really quick. He said that he was really cold. It was really unusual, and really scare me when I saw his little face and body white. He complained too that his feet where really hot that he need to take out his shoes and socks. Do you recommend to take him to a clinic or just keep observing him.? His temperature now is normal, but he really scare me. The weather is terrible right now, is in the 90 s, he drinks a lot apple juice but not soo much water,
