I've had an echo, ECG, TMT, and blood tests, and everything turned out normal, but I'm still feeling chest pain, sometimes pain in my left hand, and dizziness. Should I do these tests again, or could this all be anxiety-related? I've been through many tests before, and they keep coming back normal. Could this just be anxiety?

It's good that your echo, ECG, TMT, and blood tests have come back normal. Chest pain, left hand pain, and dizziness can sometimes be related to anxiety, but it's important to rule out any other underlying medical conditions. Since you have already done multiple tests before, I recommend consulting with a cardiologist to discuss your symptoms and previous test results. They may suggest further evaluation or prescribe medications like Ativan (lorazepam) for anxiety if needed.
