My 16 year old son woke up three days ago complaining that the center of his chest hurt whenever he took a breath or moved. Later in the day he complained of a headache and when I took his temperature he had 102 degrees. I took him to the doctor who said his chest was clear and swabbed his throat for strep which turned out negative. He still is running a fever of 101 three days later and now says his kidneys are hurting and he has loose bowels along with a dry cough, chest pain, headache. The doctor told me to bring him back in and so I am tomorrow. She thinks it is a virus. Do you think I should take him to the emergency room tonight?
