Tonsillitis typically lasts between a few days and up to two weeks, depending on the cause and type:

• Viral tonsillitis usually clears up on its own within about 3 to 7 days with rest and fluids

• Bacterial tonsillitis often requires antibiotics and generally resolves in about 10 days, with symptoms improving within 2 days after starting treatment

• In most cases, symptoms such as sore throat and fever last around 3 to 4 days but can persist longer

• Acute tonsillitis is defined as lasting between 3 days and 2 weeks

• If tonsillitis symptoms last longer than 2 weeks, it may be classified as chronic tonsillitis , which can require further medical evaluation and sometimes surgery

• Complications are rare but can prolong recovery if they occur

In summary, typical tonsillitis resolves in about a week, but bacterial cases treated with antibiotics may take up to 10 days, while chronic or recurrent cases last longer and need medical attention.
