Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more likely. But better to rule out lung diseases first. So get done chest x ray. If chest x ray is normal then no need to worry for lung diseases. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Avoid sudden jerky movements. Apply warm water pad on affected areas. Take simple painkiller like paracetamol or ibuprofen. Don t worry, you will be alright with all these in 1 week. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
