My son 6 yr old started suddenly suffering from right side headache+Fever+back pain,+throat pain+coughing+vomit sensation (2 times morning vomited cough & yellow fluid).. then rashes appeared from 2nd day on his body. With calpol fever just came little down. Cetaphil applied for rashes which is reducing But everyday his body was hot at all times..Homeopathy medicines we given till 4th day. 4th day fever increased to 103.2  so our doctor suggested antibiotic Novamox 250mg & piriton cs syrup .(till now we have given 2 days Dosage ) But today 6th day also fever is still coming in every 6 hours upto 102 to 103 range.. He becomes dull and sleep.. pls suggest is it normal ..
