Hi welcome to health care magic forum,
Tonsils are lymphoid system
which guards aerodigestive tract form common pathogens.
Any infection called tonsillitis and it could be acute follicular tonsillitis
or cryptic tonsillitis
or parenchymal tonsillitis .
In your case it seems to be follicular tonsillitis . Purple color is only appearance ,less like to bleed.
Acute tonsillitis always hurt a lot so don't worry and stop looking at mirror . Keep taking antibiotic as prescribed by your doctor.
