I'm really worried about my brother who was diagnosed with MDR TB. He went through three months of injections and took a lot of medicines for almost a year, but sometimes he still has a cough. It's not all day, but it happens occasionally. How can we check his current condition? What tests would show if the TB is completely gone? Would a chest X-ray help? He's not on meds anymore, so Im wondering if MDR TB is something that stays for life or if it can be fully treated. How long does the treatment usually last? Is it possible for him to be completely cured? I'm not sure what steps we should take next.

Pulmonologist opinion is advised to the patient.
