Non cardiac : You likely have non cardiac chest pain given your age and description of the pain, could be anxiety. Nevertheless chest pain should never be taken lightly. You should seek medical attention at your doctors clinic and get examined. They will likely get an ecg. I don't think you need a stress test but your doctor is the best determinant of that.
