Thanks for posting your query.
You are most likely suffering from acute bacterial tonsillitis
Presence of enlarged tonsil with couple of blisters along with dysphagic symptoms suggest the diagnosis.
You should consult with internal medicine specialist/ ENT surgeon and should go for thorough check up.
You should go for throat swab culture & sensitivity for detection of culprit microorganism and effective antibiotics.
Meanwhile, you should take complete antibiotic course empirically, decongestants, anti-inflammatory.
You should also perform gargles three times in day: a glass of lukewarm water with a pinch of salts.
