If chest pain still occurs after two months of taking tuberculosis treatment drugs (e.g. isoniazid, rifampicin, etc.), it is necessary to consider the possibility that Mycobacterium tuberculosis has not been completely cured or that it is combined with tuberculous pleurisy. 1. Mycobacterium tuberculosis residual: In some patients with severe Mycobacterium tuberculosis infection, the course of medication to achieve effective therapeutic effect is usually around 4~6 months. Therefore, at the end of two months of medication, there are still obvious residual Mycobacterium tuberculosis and lung infection in the body, which leads to chest pain symptoms. It is recommended to adhere to the previous anti-tuberculosis drug regimen and go to the hospital for regular checkups. 2. Tuberculous pleurisy: Some patients with tuberculosis will suffer from tuberculous pleurisy when they are infected with Mycobacterium tuberculosis, which will cause obvious chest pain or dyspnea when they breathe. Promptly go to the hospital for chest and lung CT examination, which can directly determine whether there is pleurisy attack, you can take ibuprofen and other painkillers to relieve the pain. During the treatment of tuberculosis, you should insist on taking the medication, and go to the hospital regularly for sputum culture and lung CT examination, which can directly track the effect of tuberculosis treatment.
