Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, possibility of pleuritic pain is more. Chest pain on coughing, sneezing, laughing, deep breathing is known as pleuritic pain. It is seen in lung infection like pneumonia, pleural effusion, tuberculosis etc. So better to get done chest x ray. If chest x ray is normal than no need to worry much for your pain. It is mostly due to musculoskeletal pain. So apply warm water pad on affected areas. Avoid movements causing pain. Avoid bad postures in sleep. Start painkiller and muscle relaxant drugs. Don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks
