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 heart and lung diseases for your symptoms. So get done ecg and chest x ray. If both of them are normal then no need to worry for major diseases. Apply warm water pad on affected areas. Avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Sit with proper back support. Take simple painkiller like paracetamol or ibuprofen as and when required. 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.
