I'm really worried about my brother. He's 21 and had a fever for a long time, and we found out he has TB in his neck. The doctors at the government hospital put him on a treatment with 6 rifampicin pills daily, and after 6 months the node size decreased from 43mm to 29mm. They told him to continue for another month, but after that, they didn't do any follow-up or further checkups before stopping the treatment. Is it normal to stop the treatment without checking if the infection is completely gone or if the node size has decreased more? Should we try to get more checkups to make sure everything's okay?
