Pharyngitis is an inflammation of the mucous membrane of the throat. This process can be both acute and chronic and is frequently of a viral nature, although bacterial invasion is also possible. Pharyngitis should be treated carefully, since it may cause the development of some serious complications, including heart and joint rheumatism.
Manifestations of pharyngitis vary and depend largely on the form of the disease. The acute form of the disease involves all parts of the pharynx into the inflammation process.
