According to MedlinePlus, pharyngitis usually lasts for seven to 10 days. This health problem refers to the inflammation of the pharynx, which is the organ located in between the tonsils and the larynx.
MedlinePlus states that one of the most common causes of sore throat is viral pharyngitis. This condition may arise as a part of viral infections that affect other organs, such as the lungs. Some of the most common symptoms of pharyngitis include fever, sore throat, muscle and joint pains, difficulty in swallowing and swollen lymph nodes around the neck area.
According to MedlinePlus, this condition can easily be diagnosed by a physician through a throat examination. A throat swab culture may be performed; if the results are negative, it means that the problem is not caused by a bacteria. MedlinePlus emphasizes that a patient should avoid taking antibiotics if the problem is caused by a viral infection rather than a bacteria.
MedlinePlus states that there are no specific cures for viral pharyngitis. One of the most common ways to relieve the symptoms is by gargling a solution made up of warm water and 1/2 teaspoon of salt. According to MedlinePlus, patients can also take anti-inflammatory medications if pharyngitis is accompanied by fever or if the lymph nodes are too inflamed.
