Thanks for writing your query.
After reading your post, it seems that you might be having infection of the throat and needs medical attention.
I would like to suggest that you should get yourself investigated for following :-
1. Complete Blood Count(CBC).
2. Throat swab culture.
You can take antihistamine like cetrizine
10 mg once a day along with a decongestant like phenylephrine
can be taken 6-8 hourly for fever
and body aches.
Warm saline gargles will be beneficial.
Avoid eating or drinking cold and spicy.
I hope this is helpful to you.
