Hey, I've been dealing with this pricking sensation on just the left side of my chest for the past year. It's more like a dull, mild sensation rather than outright pain, and it disappears within seconds. I've already done an ECG, echo, TMT, chest X-ray, and blood tests, and everything came back normal. Do you think I need any more tests to check my heart? Should I be worried about any heart issues even if my tests didn't show anything concerning? Also, what could be causing this pricking feeling in my left chest? Would appreciate your advice.

1) Since your ECG, echo, tmt, chest x-ray, and blood tests have all come back normal, further heart investigations may not be necessary at this point. However, if your symptoms persist or worsen, a coronary angiography may be considered by your doctor. 2) If all your tests have come back normal, it is reassuring and indicates that there may not be a serious issue with your heart. However, it is important to continue monitoring your symptoms and follow up with your healthcare provider regularly. 3) The pricking pain in your left chest could be due to various reasons such as musculoskeletal issues, nerve irritation, anxiety, or gastrointestinal problems. It is important to discuss your symptoms in detail with your doctor to determine the exact cause and appropriate treatment.
