What's the feeling of heartburn

Gastric acidity is the burning sensation, increased temperature, heat or pain that usually starts in the upper abdomen, behind the sternum. This discomfort may spread in waves towards the throat and may leave a bitter taste in the mouth. A gastric acidity is also called indigestion, acid regurgitation, heartburn or stomach acid. Is not caused by heart problems, although some of the problems of the heart can feel like indigestion.
