Welcome in H.C.M.
In reference to your medical history it appears as you are having tonsillopharyngitis. The big bumps are tonsils and nearby small erruptions are pharyngeal lymphoids.
You may take-
1- Tab Paracetamol
2- Warm saline gargling.
3- Anti histaminic.
4- Adequate fluid orally.
5- Antibiotic (preferably broad spectrum).
Probably above treatment will help you otherwise consult your ENT doctor for treatment.
