My daughter just had a CT scan done last week and the results showed that her lungs are in excellent conditions, but her sinus is very bad. I always thought that sinus is associated with headaches, bad cough, running nose, bad breath etc.... She doesn't show any of these symptoms but her doctor said that he doesn't know how she is able to smell anything.... How can this be possible? Are any of you experiencing the same diagnostic without any symptoms. Should I be considering surgery?.... Just need your opinion on this one. (She is 6 years old R553x and delta 508)
