Tonsillitis is characterized as:
If the symptoms go away on their own in less than 10 days, then it is acute tonsillitis. It is more common in children and almost every child is expected to get tonsillitis at least once.
If an acute tonsillitis infection is left untreated, an abscess or pus can form in the peritonsillar region. This is known as Peritonsillar Abscess or Quinsy.
If the symptoms of tonsillitis go away on their own, but then come back again and again after a time interval, this means you have recurring tonsillitis.
It is characterized by at least 5 to 7 recurrences in a year, 5 recurrences in two consecutive years, and three each in three consecutive years.
This usually suggests that there is an increased antibiotic resistance, which causes recurring episodes.
Chronic tonsillitis is the progressive stage of its acute form i.e., a persistent or chronic sore throat. It also causes bad breath and tender lymph nodes in the neck.
This can give birth to tonsil stones which are a hardened build-up of saliva, dead cells, and food. They need to be removed by a doctor or may come to lose on their own.
