I'm a footballer and have been experiencing mild pain in my chest and back occasionally. All tests including ECG and echo came back normal when they were done in July, but the pain hasn't really stopped and sticks around for a while. Should I consider repeating these tests? How regularly do they need to be done for someone with my level of physical activity?

Since you are experiencing mild pain in your chest and back, especially during physical activity as a footballer, it is important to monitor your heart health regularly. Considering your active lifestyle, it is recommended to repeat the ECG and echo tests annually to ensure there are no changes in your heart function. This regular monitoring will help in early detection of any potential issues and ensure your heart is healthy enough to support your extensive training.
