If there is pain in the right side of the lung, the cause of the disease should be clarified and timely treatment should be carried out, X-rays or CT of both lungs should be taken, blood routine and ultrasensitive C-reactive protein should be checked, and the diagnosis should be clarified. If the pneumonia is caused by a viral infection, drugs such as ribavirin, oseltamivir and cytarabine should be chosen for treatment. If it is a bacterial infection, sensitive antibiotics such as penicillin, amoxicillin and cefuroxime should be chosen. If the tuberculosis is caused by Mycobacterium tuberculosis infection, it should be treated early with anti-tuberculosis drugs, such as isoniazid and rifampicin. For the symptoms of lung pain, some analgesic drugs can be given appropriately, such as choosing ibuprofen, aspirin and other drugs, and regular follow-up.
