My boy is 13 years old. Two days ago she started to get flu like symptoms. He had a 102 fever, headache, weakness, etc. I took him to the doctor last night and she said he did not have a strep throat. He did not get any medicine. I have been giving him Ibuprophen and Robutussin. He has been drinking lots of water and juice. He has not eaten hardly anything today. He says that he feels like he's upside down and that something is pulling him down. Should I take him in again to the doctor to be seen?
