Thanks for your question on Healthcare Magic. I can understand your concern. Chest pain, breathlessness on exertion (walking) is commonly seen with heart diseases. So first get done ecg, 2d echo and stress test (trade mill test). If all these are normal then no need to worry for heart diseases. Sometimes simple musculoskeletal pain can also cause similar symptoms. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Avoid sudden jerky movements. Apply warm water pad on affected areas. Take simple painkiller like paracetamol or ibuprofen. Don t worry, you will be alright with all these but first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
