Hidden pain in the area of coercion and ribs may be caused by pleurisy, intercostal neuritis, lung cancer, pulmonary embolism, angina, etc., and need to be treated with medication or surgery according to the cause. 1. Pleurisy: Infection, autoimmune disease, trauma, etc. lead to inflammatory lesions such as pleural exudation, bleeding, adhesion, etc., which may cause vague pain in the area of the ribs. Antibacterial drugs such as levofloxacin, azithromycin, penicillin, ceftazidime, etc. need to be applied for treatment, and when pleural effusion is produced, it can be treated by thoracentesis. 2. Intercostal neuritis: Inflammatory lesions of the intercostal nerve due to trauma, infection and other factors, resulting in radiating pain along the intercostal nerve distribution of the intercostal space. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin can be taken for treatment. 3. Lung cancer: after invading chest wall in middle and late stages, lung cancer stimulates rich nerve tissues in chest wall, resulting in vague pain in the area of ribs, which can be treated by surgery with radiotherapy and targeted therapy. 4. Pulmonary embolism: after the pulmonary artery and its branches are blocked by blood clots from deep veins of the lower limbs, air, fat and other substances, resulting in pulmonary infarction and vague pain in the area of coercion and ribs. It needs to be treated by applying anticoagulant drugs such as warfarin, low molecular heparin, rivaroxaban, etc., or by intravenous thrombolysis or surgery. 5. Angina pectoris: coronary artery stenosis, coronary artery spasm and other factors lead to insufficient blood supply to the heart, myocardial ischemia and the emergence of coercive pain in the rib area. You can take isosorbide nitrate, aspirin, clopidogrel, resuvastatin and other drugs. There are many other reasons for the hidden pain in the area of coercion and ribs, so consult a doctor as soon as possible, complete the examination, clarify the cause of the disease, and target treatment.
