Chronic pharyngitis generally does not cause fever. The symptoms of chronic pharyngitis are various, with the most common being sore throat, a sensation of a foreign body in the throat, and burning sensation. Some patients might also experience nausea and vomiting. However, it generally does not cause fever. If it is an acute episode of chronic pharyngitis, it could possibly be due to an acute bacterial infection or inflammation, which might lead to fever. Some patients might even exhibit high fever, and it is necessary to consider timely medical treatment. At the same time, physical cooling can be used in conjunction with medication. Generally, through standard medical treatment, conditions can gradually recover and relieve. (Please administer medication under the guidance of a professional physician and do not self-medicate blindly.)
