Pharyngitis is inflammation of the throat, between the tonsils and the larynx. This disease can be acute or chronic. Acute pharyngitis usually subsides in a week and is caused by a viral or bacterial infection with symptoms of sore throat, fever, and rash, redness of the throat, swollen lymph nodes, headache, and difficulty swallowing. Depending on the source of the infection, the treatment involves antibiotics or drugs to relieve symptoms, rest, drinking hot liquids or gargling. Patients with weak pharyngeal mucosa are more predisposed to chronic pharyngitis. This can be caused by excessive heat or cold, dry environments, exposure to smoke, and mouth breathing (vs breathing through the nose, among others. The symptoms are a feeling of dryness, discomfort in swallowing, coughing or hawking. Treatment of chronic pharyngitis seeks to alleviate symptoms and is based on avoiding adverse environments and factors that worsen the condition. When it occurs repeatedly and causes serious complications, the patient may require surgery.
