Having a violent cough can involve the intercostal muscles, which can easily cause strong contraction of the local muscles and can easily cause pain. The cause of the cough needs to be actively treated. If there is a dry cough without sputum, you can take oral dextromethorphan granules, dihydrocodeine, and in case of bacterial infection, you need to treat it with effective antibacterial drugs, such as amoxicillin or roxithromycin. If the pain is severe or there is a fever, you can also use acetaminophen, ibuprofen and other drugs to relieve fever and analgesia, and you can also use hot towels to relieve local pain. In most cases, the pain will be relieved when the coughing stops. If the pain continues, it should be considered to be caused by pleurisy or intercostal neuralgia, and it is best to go to the hospital for an examination to identify the cause before using medication.
