Thanks for writing your query.
After reading your post, it seems that you are having some congestion in your throat.
You should get a throat swab culture done.
In addition to antibiotics (according to throat swab culture/senstivity reports), you should also take antihistaminic like Fenofexadine
120 mg once a day along with decongestant like phenylepherine.
Warm saline gargles will help you in in relieving your symptoms.
Any medicine to be taken under medical supervision only.
If the problem persists, get your throat examined by an ENT specialist
to rule out a possibility of tonsillar stone.
I hope this is helpful to you.
