Persistent cough. Me what should i do.

Hi, I am 36 years old female. Around a month back I felt small itching in my throat and after two days I started coughing terribly. I took home remedies like ginger, warm water, Benedril. But nothing helped. So after 10-12 days I visited general physician. He prescribed me Augmed 625, moncel L, and cough syrup awexDx. Even taking these for five days nothing improved. Then I visited ENT specialist and he gave me Refzil O, Allegra. I took Allegra for few days and then I started with Refzil O. It's been four days but I still have cough. Though severity is not that much. I spit out greenish mucus whenever I cough. My eyes burn a little bit and my forehead feels little heavy. Please advise me what should I do. Thank you for your time.
