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.
