I'm a 20-year-old female dealing with active pulmonary tuberculosis, and I've been on treatment for about 1.5 months now. The doctor said my x-ray shows that 70% of my lung is damaged, and there are large cavities. I'm having severe white-colored cough that just won't quit, and I'm exhausted all the timeI can't even stand without feeling the need to sit down. Any exercise or even short walks wipe me out completely. Given that I've been on medication for a while now, shouldn't the severe cough have improved by now? Is there any chance my lungs can heal and return to their previous state without cavities? And this tirednesscould it be a side effect of the anti-tuberculosis medicine I'm on?
