I'm really worried about my wife. She's been on TB treatment for a month now, but her cough hasn't really gotten any better. Her appetite seems fine, and she's even gained a few kilos. There's no fever or sweating, which is good, but the bloody cough and irritation are alarming and she's feeling really fatigued. Her chest X-ray shows sputum negative. What could be going on, and what should we do next?

It's good to hear that your wifes appetite is improving and she has gained weight. However, the persistent cough, fatigue, and blood in the sputum should be monitored closely. I recommend consulting her doctor to reassess her treatment plan and rule out any complications or need for further investigation, as these symptoms may require adjustment of her therapy or additional tests.
