What can cause throat canker sores and how to cure them

A throat canker sore consists of a small, round, whitish wound in the center, reddish on the outside, which causes pain and discomfort, especially when swallowing or speaking. In some cases there can be other symptoms present such as fever, malaise and enlargement of the neck ganglia.

This type of canker sore may arise after ingesting acidic food or can be the first sign of a weakened immune system, and may therefore appear when you have herpes after a cold. When canker sores are very big and take a long time to heal they can indicate the presence of a more serious disease such as AIDS or cancer.

The doctor may prescribe ointments for treating throat canker sores and suggest you avoid consuming acidic foods, for example. Another suggestion is to gargle warm water and salt which may relieve discomfort.
