What to expect if I have Tonsillitis  (Outlook/Prognosis)?
Tonsillitis symptoms usually improve 2 or 3 days after treatment starts. The infection usually is cured after treatment is completed, but some people may need more than one course of antibiotics.
Complications of untreated strep tonsillitis may be severe. Children with tonsillitis related to strep throat or pharyngitis should generally be kept home from school or day care until they have been on antibiotics for 24 hours. This helps reduce the spread of illness. </s>
