tonsils that have an abscess can certainly "burst". severely enlarged tonsils from mono may seem deflated once they retreat back to their pre-mono size. i have no way of seeing your tonsils as you know so i cannot blindly determine if what you are seeing is normal or not. you would need to see your medical provider for an examination.
can your tonsils burst? . i had tonsilitis with mono. my tonsils were very swollen but now after healing it almost feels like my tonsil deflated and is just sitting there. should i be concerned?
