For a few nights, I have been waking up with dull pains on the left side of my chest (it feels like a heart cramp). What should I do, is this an emergency?

It is important to take chest pain seriously, especially if it is new, sharp, or persistent. If you are experiencing chest pain along with other symptoms such as fever or shortness of breath, it is recommended to seek immediate medical attention. Contact your healthcare provider or go to the nearest emergency room for a proper evaluation and treatment.
