Throat Pain. Feel discomfort in throat?

I had dry throat for 5 days no pain while swallowing. From 6th day I had throat pain at right side, I started gargling and steam. 7th day I felt something is stuck in the throat and pain too. I have swallowing saliva often because of this. I consulted online General Physician he said it's acute pharyngitis and gave me Augmentin 625 for five days twice daily and betadine gargle. Now it's total 14 days since it started I feel little better after taking tablets for five days but still I feel something there in throat. I told this to Doctor told me to continue with gargling and steam alone. Should I be worried? Will this go away slowly or need to check an ENT to see why I still feel discomfort in throat? Please advice
