Burning and mucus in throat, strained voice

Ears, nose and throat
1

I've had burning throat, mucus and a strained voice for 4 weeks now. 

I've tried using anti-inflammatory (Naproxen) medication for 1 week and didn't work

I've tried gargling salt water and drinking honey and didn't work 

Went to an ENT and they told me to take anti biotics for 5 days, i've taken 2 (still 3 days left) and there's no difference 

I've doing voice rest for 2 days and I there i still feel my voice is strained 

I've also tried to change my diet for LPR and took anti-acids and it's the same

Help, please!

Did they check for strep infection ? or 

It may be glndular fever, but you did not say you have fatigue or fever.
