Hello and welcome to HCM,
You are suffering from acute pharyngitis
which is often bacterial or sometimes viral infection leading to inflammation of the mucuous membrane lining the throat. your peritonsillar crypts seems to have inflammed.
I suggest you to start with an antibiotic course of Augmentin
625mg along with NSAIDs serratiopeptidase
tablet twice daily for about 5 days.
Gargling with lukewarm saline water or antiseptic mouth rinse like chlorhexidine
mouthwash 3 to 4 times daily will give soothing effect.
i hope this helps you, take care.
