Thanks for writing your query.
After reading your post, it seems that your symptoms are suggestive of having viral fever
which will subside in 5-7 days time.
Still you should get following investigations to rule out any bacterial cause :-
1. Throat swab culture.
2. Complete Blood Count(CBC).
You can take antihistaminic like Fenofexadine
120 mg once a day along with decongestant like phenylepherine for relief from your symptoms. Paracetamol
can be taken for fever or headache.
Antibiotic, if needed, can be added according to the reports of the investigations
You should take any medicine after getting yourself clinically examined by your doctor.
I hope ths is helpful to you.
