Severe suppuration of the throat has more causes, and how long the patient will recover is related to his specific condition and cannot be generalized. Severe suppuration of the throat may be caused by purulent inflammation of the tonsils, often caused by pneumococcus, streptococcus, staphylococcus aureus and other bacterial infections, the course of the disease is relatively long, and some patients can only gradually recover after 2 weeks of anti-infection treatment. For herpetic pharyngitis caused by viral infection, patients with pus after herpes outbreaks, the general course of the disease is usually about 1 week, and need to apply antiviral drugs for symptomatic treatment. Patients should be aware that too short a period of treatment may lead to incomplete killing of pathogens, triggering recurrent episodes. In addition, if the patient’s resistance is poor or not treated in time, the purulent infection is prone to prolongation, thus manifesting the symptoms associated with chronic inflammation, and its recovery time can be prolonged. Therefore, patients with severe suppuration of the throat should go to the ENT department in a timely manner to clarify the cause of the disease and carry out symptomatic treatment.
