Thanks for visiting HCM.
You are very right that pulmonary tuberculosis
usually heals by a process called fibrosis
and the site mostly is right upper lobe, many a times both upper lobe. The role of a clinician is to distinguish between active disease and healed one.
Reactivation of the disease accompany symptoms like cough of any type, bloody sputum, weight loss
, evening rise of temperature, night sweats
The easiest, cost effective and confirmative is to go for two sputum samples for acid fast bacilli examination. So I recommend you for this test, and is readily available at designated microscopy centres.
Your second query is regarding asthma
. There is no increased risk for developing tuberculosis with inhalers and you can safely continue with your anti-asthma medicaton.
