I often have a dull ache in the heart area, when I exercise strongly, I have angina, there is 1 time of 15 minutes of angina and every time I take a deep breath, it hurts, the back of my lungs is also dull. I went to the doctor, had a chest x-ray, but nothing abnormal was found. After reading it, I feel like the symptoms of coronary heart disease. So the doctor asked me what are the symptoms of heart, lung, and angina pain? How is the treatment?

When I woke up in the morning, I suddenly felt a sharp pain in the heart area and pain through the back. I straightened my back and took a deep breath, it hurt. Sometimes I get like that. Can you advise me what heart pain is a sign of disease?
