HI I have gone through your mail and as you said that your child is having fever
reaching up to 40 or 41 ,his ears are o.k as told by your doctor but now he has cough
with running nose and greenish stool. Considering your complaints it appears that your child is having fever due to either respiratory tract
infection or abdominal infection. thus you are advice to go for these investigations- (1) X-Ray chest P.A.view, (2) culture & sensitivity of throat swab,(3) Blood- CBC, ESR, MP,widal test
, (4) urine - routine and microscopic, Urine culture & sensitivity, (5) stool examination. beside this child should be physically examined by an E.N.T.specialist and Pediatrition to find out the actual cause of fever and than treatment. Thanks.
