The disease rarely manifests itself as an isolated inflammation. Most often, it begins on the background of other infectious diseases of the respiratory tract like acute respiratory viral infection or influenza.
The patient experiences pain when swallowing and complains of sore throat and rawness. Commonly, there is no pain when swallowing food, but it appears and strengthens during swallowing saliva.
The pain may radiate to the ears. This occurs when a greater part of the throat is involved in the inflammation process.
