Thanks for your question on Healthcare Magic. I can understand your concern. No need to worry for heart diseases as your ecg is normal twice. So no need to ga for angiogram. By your history and description, possibility of simple musculoskeletal pain is more. You might be sleeping in bad awkward position which is causing this pain in morning only. This pain improves when you relax. This also favours musculoskeletal pain. So avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Apply warm water pad on affected areas. You can take simple painkiller like ibuprofen if pain is more. 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.
