hi my son is 2 yrs old..some 13-14 days back..he had fever (between 100-100.4 F) with cough and runny nose...the doc prescribed crocin suspension syrup (acetaminophen) for fever, cefixime oral suspension as antibiotic and syrup of cetrizine hydrochloride and ambroxol hydrochloride for cough and cold...for 5-7 days...The fever got over after 4-5 days and cough and cold considerably reduced. Day before yesterday my child again developed fever. the doc says it is viral...can the viral fever subside and reoccur again after 10-12 days or should we get the blood tests done..the fever still fluctuates between 100-100.4 F when measured under the arm.
