I'm experiencing heaviness and palpitations in my chest along with heartburn. I've gone through several tests like ECG, Echo, stress TMT, and stress MPI, and they all came back normal. But I still feel these symptoms sometimes and have visited many cardiologists without finding a solution. They say it's anxiety, yet I sleep well at night. Do you have any advice or suggestions for further tests? And is it okay if I drink chamomile tea at night?

It's good that you have undergone various cardiac tests which have come back normal. Since your symptoms are still persisting, it is possible that anxiety could be contributing to your symptoms. In addition to managing stress and anxiety, you can try over-the-counter antacids for heartburn relief. For palpitations, you can try taking a magnesium supplement. However, it's important to consult with a doctor before starting any new supplement. As for chamomile tea, it is generally considered safe for most people and can help with relaxation. You can try drinking chamomile tea in the evening to help with anxiety and promote better sleep. Start with a low dose and see how your body reacts to it. If your symptoms continue or worsen, it may be helpful to consult with a gastroenterologist to rule out any gastrointestinal issues that could be contributing to your symptoms.
