Hi thanks for contacting HCM... You are having very young age .... You are suffering from repeated pneumonia Infection.... So your immunity might low ...Also look for diabetis in which chances if infection high . If diabetis present drugs for that started..... This last time your infection might be severe and spread through blood into liver so liver enzymes were high .. Bacteremia sometime can lead bone marrow involvement , so wbc count was low .... At that time I.V antibiiotic infusion given according to blood culture report .... If breathing severely impaired at that time oxygen level should be checked in blood ... Take care . Advise : pulmonologist consultation for examination
