Thanks for your question on Health Care Magic. I can understand your concern. Chest pain on coughing is known as pleuritic pain. And common causes of pleurisy are lung infection, pleural effusion, Pulmonary infarction etc. So better to get done chest x ray first. If chest x ray is normal then no need to worry for these causes. Musculoskeletal pain can also cause similar kind of chest pain. So apply warm water pad on affected areas. Avoid movements causing pain. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Start painkiller and muscle relaxant drugs. Don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
