HI,
Thanks for posting your query.
You are most likely suffering form
Acute bacterial tonsillitis.
Presence of enlarged left sided tonsils along with pus pint suggests the diagnosis.
Circumvallate papillae are very close to
adenoids (a collection of lymphoid tissue on the back of tongue) and enlarged during any sort of infection.
You should consult with internal medicine specialist/ ENT surgeon and should go for thorough check up.
You should also go for throat swab culture & sensitivity.
You should take complete antibiotic course and analgesics.
You should also perform gargles with lukewarm water along with a pinch of salt.
Avoid sour, curd,
cold drinks and oily food.
Take care,
Dr. Mayank Bhargava
