Pain on swallowing food and fluids, a symptom often due to disease of the Oesophagus.
The pain may stem from the mouth, throat (pharynx) or Oesophagus (gullet). At times, odynophagia may also be related to the larynx. The mechanism of swallowing is both voluntary and involuntary and starts in the throat and extends to the Oesophagus.
While pain during swallowing may be felt in the mouth or throat (oropharyngeal causes), esophageal causes of odynophagia may present as chest pain.
