Fever caused by pharyngitis has persisted for nearly three days with no improvement, which is a bit concerning. How many days does it usually take for fever due to pharyngitis to resolve?

Sore throat and fever usually take about 7 days to resolve, with body temperature returning to normal. The first consideration should be the common cold, which causes upper respiratory tract infection; another possibility is suppurative tonsillitis, as the treatments for these two conditions differ significantly. The common cold is mainly managed with symptomatic treatment, whereas suppurative tonsillitis requires prompt antibiotic therapy.
