Intercostal neuralgia after lung surgery is mainly closely related to nerve injury, and further treatment mainly includes oral medication, closed treatment and physical therapy. 1. Oral medication: Oral painkillers, such as ibuprofen, can be taken for severe pain, and nerve-nourishing drugs, such as methylcobalamin, can be applied. 2. Closure therapy: If the pain is intolerable, local closure (a mixture of lidocaine, glucocorticoids and saline) can be used. 3. Physiotherapy: Mostly through deep heat therapy, etc., to promote local blood circulation, which will help the aseptic inflammation subside. Intercostal neuralgia is a common complication after lung surgery. Most of them can be recovered gradually, and if they are not relieved all the time, they need to consult a doctor for observation and standardized treatment under the guidance of a clinician.
