In short
Most tonsillitis is viral and settles in three to four days without antibiotics. The value of seeing a doctor is separating the minority that is bacterial and spotting quinsy, which is an emergency.
Emergency if: Difficulty breathing or swallowing saliva, drooling, difficulty opening the mouth, or swelling inside the mouth and throat — emergency care now.

What it is and how long it lasts
The tonsils sit at the back of the throat and are part of the immune system, sampling what enters the mouth and nose. Tonsillitis is inflammation of those tissues, producing a sore throat, pain on swallowing, swollen tonsils often with white patches, tender glands in the neck, fever, and sometimes ear pain referred from the throat.
Symptoms of tonsillitis usually go away after 3 to 4 days but can last longer. That timeframe is the useful benchmark: an illness following that course is behaving as expected, while one that is worsening after three or four days, rather than easing, is the one worth reassessing.
03
Treatment that actually helps
For viral tonsillitis the aim is comfort and fluid intake. Regular paracetamol or ibuprofen at appropriate doses does more than most people expect, particularly taken on schedule rather than only when pain peaks. Cool drinks, soft foods, and adequate fluids matter because pain on swallowing leads quietly to dehydration, especially in children.
If antibiotics are prescribed for confirmed bacterial tonsillitis, the full course is completed even though you feel better within a couple of days, as treatment reduces the small risk of complications. Antibiotics do not shorten viral tonsillitis and bring side effects, which is why not being given them is often the right outcome rather than a brush-off.
04
Quinsy and other complications
Quinsy is a collection of pus beside a tonsil, and it is the complication that turns tonsillitis into an emergency. Call emergency services or go to an emergency department for a severe sore throat that quickly gets worse, swelling inside the mouth and throat, difficulty speaking, being unable to swallow, difficulty breathing, or difficulty opening the mouth.
Being unable to swallow your own saliva, drooling, a muffled voice, or the pain being clearly worse on one side are the practical warning signs. Quinsy needs draining and does not settle with oral antibiotics alone. Other complications are much rarer but include infection spreading into the deeper tissues of the neck.
05
Recurrent tonsillitis and surgery
Repeated attacks are a genuine burden and surgery is considered when frequency reaches a threshold that outweighs the risks of an operation — typically a high number of well-documented, disabling episodes over one to two years rather than occasional sore throats. Keeping a simple dated record of episodes and time off work or school is what makes that assessment possible.
Two situations deserve separate mention. A sore throat with marked fatigue, widely swollen glands and a large spleen may be glandular fever, where a particular antibiotic class causes a florid rash and heavy contact sport is avoided for weeks. And a sore throat with unusual bruising, extreme pallor or a rash that does not fade under pressure needs urgent assessment for other causes entirely.
When to act
Routine — see a doctor
Sore throat with fever settling over 3 to 4 days: regular painkillers, cool fluids and rest, without antibiotics.
Same-day — call promptly
Symptoms clearly worsening after 3 to 4 days, not drinking enough, pain much worse on one side, or a very high temperature.
Emergency — act now
Difficulty breathing or swallowing saliva, drooling, difficulty opening the mouth, or swelling inside the mouth and throat — emergency care now.
