Tonsillitis - What Happens

What Happens

Tonsillitis caused by a virus typically lasts 4 to 10 days; a bacterial infection lasts slightly longer. If symptoms include sore throat, fever above 101° (38.3°), and swollen lymph nodes, the infection might be caused by strep bacteria. Strep throat, which must be diagnosed by a health professional, requires antibiotic treatment.

In some cases, tonsillitis can become chronic. Surgical removal of the tonsils (tonsillectomy) may be recommended for you or your child based on past health and results of physical exams.

Complications of tonsillitis

Tonsillitis caused by strep bacteria that is not treated with antibiotics may result in complications, such as ear and sinus infections or pockets of infection outside the tonsils (peritonsillar abscess). More serious complications, such as rheumatic fever, may also occur.

Recurrent and ongoing (chronic) tonsillitis may obstruct the upper airway and cause problems, such as snoring, nasal congestion, and mouth breathing. Sometimes, chronic tonsillitis can lead to more severe conditions, including obstructive sleep apnea and heart and lung problems. But most children with sleep apnea and enlarged tonsils do not have a history of tonsillitis.
