I'm having this weird throbbing pain in my chest that feels like getting punched, but it only lasts a few seconds and then disappears. It pops up unexpectedly and can be on the left, right, or center of my chestnot in one specific spot. It doesn't happen when I'm exercising, but when it hits, it's in this tiny area that I could touch with a finger. I've had an ECG and three 2D echo tests, and all the results look fine according to the doctors. I'm really confused about what's causing this. Any idea on what might be going on?

It sounds like you may be experiencing episodes of chest pain known as angina. Angina is often described as a squeezing, pressure, heaviness, tightness, or pain in your chest. It can be caused by reduced blood flow to your heart muscle, which is usually due to coronary artery disease. Since your ECG and 2D echoes have come back normal, it is good news that there is no immediate concern for heart-related issues. However, it is still important to investigate further to determine the cause of your chest pain. I recommend discussing with your doctor about the possibility of undergoing a stress test to evaluate your heart's function under stress. Additionally, you may benefit from a CT coronary angiography to assess the blood flow in your coronary arteries. In the meantime, to help manage your symptoms, your doctor may prescribe medications such as nitroglycerin to relieve chest pain. It is important to take the medication as prescribed by your doctor. Remember to follow up with your healthcare provider for further evaluation and management of your chest pain.
