Hello, Thanks for posting on HCM, Before all fever of unknown origin it is always very important for the doctor to investigate on the cause and treat (as there is always an underlying cause mostly infection). First of all you need to get the child to a pediatrician or if you prefer your present doctor it is still fine. Your child will need to undergo complete physical exams (including otoscopy exams), blood tests such as CBC, CRP, urinalysis, malaria test (if in endemic zone), serum chemistry, blood cultures etc Doctor has to rule out viral infections, rheumatic diseases (e.g juvenile rheumatoid arthritis), parasitic blood infections, tumors, endocarditis, hepatobiliary infections etc etc. Ones the cause is determined, the appropriate treatment will be provided by his doctor. The present treatment he is having Dolo suspension and meftal-P are only for treatment of fever and not the cause. Hope this helps
