Hi, may I answer your health queries right now ? Please type your query here... My child started a fever 6 weeks ago with the flu. Since then, he has been on 2 rounds of antibiotics for sinus infections. We just finished the last dose when the low grade fever reappeared. There is nothing that gives the indication that he still has a sinus infection and he acts completely normal. Is it possible that inflammation is causing a low grade fever rather than an infection.

### output:

Dear user we know that recurrent fever or prolonged fever or fever of unknown cause resembles worry to every person but we should not get worry and try to find the cause.......your child was having sinus infection then he took two types of antibiotics that may lead to bacterial resistance of antibiotics as administration of different types of antibiotics causes the bacteria to accommodate and get resistance...........may be your child have another bacterial infection rather than sinusitis and not treated.........simply you should do urinalysis test for him to investigate if there is urinary tract infection or not ....also you should do tidal test to indicate if there is typhoid disease that causes recurrent fever... another test to do is blood culture test ....low grade fever reappears means that there is bacterial infection that is not diagnosed until now ....doing these three simple tests will help a lot and try to see your doctor infectious disease specialist or pediatrician...........also you should notice your child if he has any troubles rather than fever such as changing urine color or diarrhea or constipation or any rash appears on him, and please send to us about that...we can help reach diagnosis ........and any abnormal symptom you notice will lead us to the correct way of diagnosis and treatment..............I wish your child happy healthy life
