My mom is suffering from some kind of a lung disease. She gets pneumonia often. Her both lungs get collapsed and after treatment it gets better. But, it's not curable that's what her specialist doctor says. She had tb 5 years back for which she took tablets for 6 months and then it went away. Recently, she again had this infection that caused fever with difficulty in breathing. Doctor said that tb has come again, and prescribed tablets for 9 months. Culture test was negative. My mom gets hungry and did not lose weight normally. Yes, she lost some weight when she was totally sick for about 2 weeks. But prior to that she had no weight loss. We wanted to take a second opinion , there they said it's not tb. Culture tests and symptoms are negative for tb. Still, xray and ct scan results look like tb. Even the doctor is unsure and said we can wait and see. The doctor prescribed combunex for 6 months. Please help. We don't want my mom to take tb tablets if she doesn't really have tb. I guess, that tb medicines could affect her other organs if taken without having tb disease. So, I request your help and advice how do we go with this. Please let me know if you want more information about her medical records. Thanks in anticipation.
