What Causes Persistent Fever While Suffering From Strep Throat?

my 8 year old son has had a fever since last wednesday (a week ago tomorrow) that has spiked as high as 104-105. We controlled it by alternating advil and tylenol every 3 hours and that was for 4 days. We took him to the Dr. on Sunday and they confirmed strep throat. The only real symptom has been this high fever, and he hasn't complained about anything else. He did vomit once and it was greenish/yellowish and looked like mucus. He is now on Amoxicillin for 10 days, and my big concern is that his fever is not going away. It has been spiking in early evening and early morning as high as 103, so we've still been giving Advil/tylenol. what do you think? could there be a secondary infection or complications because we let it go for several days before treatment?

Hi,
after going through the medical history I feel that the infection is resistant to Amoxicillin. Usually fever subsides within 1 or 2 days of antibiotic therapy. Unless the bacteria is resistant, it is not possible for the fever to be going on till now. The other possibility is that an entire diagnosis has been missed altogether. Why I say this because, Strept can also be cultured from healthy people who are called as carriers and they do not have symptoms because of this. Therefore it may be co-incidental that we identified this carrier state when he might be actually down with something else. (This is not a common scenario when compared to encountering an antibiotic resistance). So next spike of fever, Kindly take your son to ER and it is better to get him admitted in the hospital, do blood and urine test and cultures and treat accordingly after ruling out other infections
