Thanks for your question on Healthcare Magic. I can understand your concern. Since you are having history of lung nodules, we should definitely rule out lung diseases for your symptoms. So get done chest x ray. If chest x ray is normal then no need to worry for lung diseases. Musculoskeletal pain due to costochondritis can also cause similar symptoms. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Apply warm water pad on affected areas of chest. Take simple painkiller like paracetamol or ibuprofen. Don t worry, you will be alright with all these. Avoid stress and tension, be relax and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
