Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, possibility of musculoskeletal pain is more. But better to rule out lung related causes for your pain. So get done chest x ray. If chest x ray is normal than no need to worry for lung causes. And your pain is mostly due to musculoskeletal cause. So avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Avoid bad postures in sleep. Take painkiller and muscle relaxant drugs. Warm water pad application on affected area is also helpful in such cases. And avoid coccain intake as it is not good for health. So don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
