My 7 month and 10 days old son is suffering from above mentioned symptoms from more than 15 days, i have visited 3 to 4 doctors but there is no improvement in his condition, when i visoted fifth doctor he directly told us that he had pneumonia and suggested for blood and x ray examinations. Is it fever, coughing and running nose are the enough confounding factor to diagnose pneumonia. Pls reply ASAP.
