I've been experiencing this weird, needle-like pain on the left side of my chest for over a month now, about 34 days to be exact. It comes and goes, and it's really starting to worry me. I got an ECG done, but it came out normal. Should I be concerned, or is there something else I should be looking into?

It sounds like you may be experiencing symptoms of angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood. Since your ECG is normal, it's good news that there may not be any major heart issues. However, it's still important to address the symptoms you are experiencing. I recommend taking a low dose of aspirin (75-100mg) daily to help reduce the risk of blood clots and improve blood flow to the heart. Additionally, you can try using nitroglycerin sublingual tablets as needed for chest pain relief. It is important to rest and avoid strenuous activities until the symptoms improve. If the symptoms persist or worsen, please seek medical attention for further evaluation and management.
