Hello doctor, I suffered from MDR tuberculosis in 2012 and completed the treatment and got fully cured in 2014. My problem is whenever I do deep breathing, there is a pain in my lungs (left part). There is always an irritation (which kich) in my throat with phlegm. Why is this happening and why is there a pain in left part of my chest? P.s - I suffered from tuberculosis in 2010 also and completed the treatment.
