Hi @harryhuse, a warm welcome to Connect. Chest pain for 3 weeks in a row is concerning. You'll notice that I did move your concern over to an ongoing discussion about chest pain and pressure. This is so you can connect with other people who might be experiencing chest pain like you are.

This is an article on when you need to call 911 or your doctor depending on what your symptoms are.

Did your cardiologist recommend that you do a 24 hour holter monitor to check your heart? The ECG may not have given your doctor enough information in the short time it takes to do the test.
