Thanks for your question on Healthcare Magic. I can understand your concern. In my opinion, you are mostly having musculoskeletal pain because your symptoms are associated with specific position. But better to rule out cardiac chest pain as you are above 60 years. So get done ecg and 2d echo first. If both are normal then no need to worry for heart diseases. Sit with proper back and chest support. Avoid heavyweight lifting and strenuous exercise. Avoid sports for few days. Avoid bad postures in sleep. Apply warm water pad on affected areas. Rake simple painkiller like ibuprofen. 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.
