Thanks for your question on Health Care Magic. I can understand your boyfriend s situation and problem. By history and description, possibility of musculoskeletal pain is more. But better to rule out pleuritic pain. Lung infection - pneumonia is the most common cause for pleurisy. So get done chest x ray. If chest x ray is normal then no need to for pneumonia. He is having mostly musculoskeletal pain. So ask him to avoid heavyweight lifting, strenuous exercise. Avoid movements causing pain and bad postures in sleep. Ask him to take painkiller and muscle relaxant drugs. Warm water pad application on affected site can be helpful. Don t worry, he will be happy. Hope I have solved your query. Wishing good health to your boy friend. Thanks.
