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 get done chest x ray to rule out lung related diseases. If chest x ray is normal then no need to worry for lung diseases. Apply warm water pad on affected areas. Avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Sit with proper back support. Take painkiller and muscle relaxant drugs like ibuprofen and thiocolchicoside. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
