Hello Doctor! My mom showed symptoms like fever, cough, cold, malaise, for around a week. She went to doctor and had some tests done and they were not very sure of the diagnosis. Sometimes they would say TB, sometimes no TB. So they sent my mom to a better hospital and doctor and after a full checkup including sputum, imaging tests like CT scan, AFB, PPD skin test etc, doctor came to the conclusion that she doesn't have TB. Since then she is fit and fine, but my concern is that she is still coughing. Should I be worried? She also had cough before like we have usual cough which worsens in the winter. She is very susceptible to cold. My other family members are saying that that the frequency of her coughing is normal, but I think it is not normal. Please guide. Thanks
