This nerve stimulation results most commonly in heartburn
, the pain
that is characteristic of GERD. Heartburn
usually is described as a burning pain
in the middle of the chest. It may start high in the abdomen or may extend up into the neck. In some patients, however, the pain may be sharp or pressure-like, rather than burning. Such pain can mimic heart pain (angina). In other patients, the pain may extend to the back.
