Thanks for your question on Healthcare Magic. 
I can understand your concern. 
In my opinion, we should rule out bronchitis in your case. 
Bronchitis (inflammation of airways) is common after 
lung infection like 
tuberculosis. 
Bronchitis can cause breathing difficulty. 
So get done PFT (pulmonary function test). 
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only. 
You will mostly improve with inhaled 
bronchodilator (formoterol or salmeterol) and inhaled 
corticosteroids (ICS) (budesonide or fluticasone). 
In Sion Hospital, Dr. Awad is in 
pulmonary medicine department. You can consult him and discuss all these. 
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
