Thanks for all these additional information.
I understand your concern.
I have reviewed your picture.
Well as you describe,possible causes may include Strep throat,Tonsillitis.
So you need antibiotics prescription from your doctor in person.
In the meantime you can take some self care measures like
Take OTC Motrin and Claritin.
Also drink warm liquids.
Start a multivitamin supplement.
Also do steam inhalation and saline gargles.
Betadine oral rinse twice a day can be effective.
You should avoid spicy,fat rich food,carbonated beverages.
Nasal saline spray can be tried.
See an ENT specialist for further evaluation and management.
