Acute pharyngitis is mainly caused by acute viral or bacterial infection, leading to inflammation and resulting in the swelling and reddening of the mucous membrane in the throat. Common symptoms include sudden onset of throat pain and swelling. If the inflammatory response is significant, it may also be accompanied by fever, difficulty swallowing, a sense of obstruction, or breathing difficulties. Generally, it is a common disease. It may be advisable to conduct a laryngoscopy to inspect the extent of inflammation in the throat and perform a routine blood test to determine whether it is an acute bacterial or viral infection. In terms of treatment, oral medication is usually preferred, and nebulization or traditional Chinese medicine can be considered to target the infection. (Please use medication under the guidance of a professional physician and do not self-medicate.)
