Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain due to vigorous coughing is more likely. Vigorous coughing can cause straining on ribs and intercostal muscles. This can cause soreness. So follow these steps for better symptomatic relief in musculoskeletal pain. 1. Apply warm water pad on affected areas of chest. 2. Give him painkiller and muscle relaxant drugs like ibuprofen and thiocolchicoside. 3. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Don t worry, he will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
