After being on tuberculosis treatment for 2.5 months, I've started coughing up blood. What could be causing this, and what should I do?

After 2.5 months of TB treatment, blood coming from the mouth after coughing could be a sign of a serious complication known as hemoptysis. This can occur due to damage to the lungs caused by the TB infection. It is important to address this issue promptly. I would recommend you to consult your healthcare provider immediately for further evaluation and management. In the meantime, continue with your TB treatment as prescribed. Your doctor may consider adjusting your treatment regimen or providing additional medications to help control the bleeding.
