Thanks for posting your query.
You are most likely suffering from acute bacterial tonsillitis
You should again consult with treating ENT surgeon and should take complete antibiotics course, anti-inflammatory and decongestants.
You should also perform gargles three times in day with lukewarm water and a pinch of salt.
You should avoid sour, cold
drinks, oily food and yogurt.
If your condition won't improve after taking these antibiotic then you should go for surgical treatment
