Heartburn is a feeling of burning, warmth, heat, or pain that often
starts in the upper abdomen just beneath the lower breastbone (sternum). This
discomfort may spread in waves upward into your throat, and you may have a sour
taste in your mouth. Heartburn is sometimes called indigestion, acid
regurgitation, sour stomach, or pyrosis.
