I had cold, cough and fever a few days ago. Took Azithromycin 500 for 5 days. Thereafter on the last day of antibiotics, I coughed up blood with phelgm twice. Thereafter no blood, but after two days there was blood once in my nose mucus. Went for a Chest X ray on the suggestion of a Doctor. On seeing the X-RAY the doctor told me that I need immediate CBC, CT scan as my lung condition is very bad. My x-ray report only shows mildly prominent bronchovascular markings and horizontal fissure. On consultation with another doctor I was told it is common in old age and especially when you have cold and cough. I have been given antibiotics, steroids and cough syrup again. Is the X ray really bad? I have attached the photos. Do I really need a CT scan of lungs? Please suggest Doctor. I am really worried.
