Thanks for your question on HCM. Since you have not completed the course of anti TB drugs in 2007, it is likely to have reactivation TB now. TB is chronic infection and needs atleast 6 months treatment. If you not taken full treatment the TB bacilli in the body are not completely killed. They remained silent in the body only to reactivate in future. And your recent chest x ray is worsening which also favours reactivation. I suggest you to consult pulmonologist and get done 1. CT Thorax with contrast. 2. Bronchoscopy and BAL analysis for AFB and AFB culture and sensitivity to rule out drug resistant TB.
