my mom was diagnosed with bacterial pneumonia back in late december. After a round of antibiotics, she felt much better but the xray still showed pneumonia. A round of stronger antibiotics were then given to her. She went back for a follow up xray last week and the xray now shows the pneumonia is in both lungs. The strange thing is...she has NO symptoms. No coughing, no fever, nothing. Could it possibly be viral? or fluid? or cancer???? Btw she has never smoked in her life.
