Constant cough with breathing problem.

Hi, I got this sore throat 2-3 weeks ago which got me cold and fever too. To avoid I had okacet cold and hifenac p for a day or two and it didn't help much. Then after few days I visited a doctor who prescribed hifenac p, becosules z and azeee 250 which help for the time being.     At the same time I was travelling to Delhi n Himachal during my medicine course and got the sore throat again and at that time I jave taken medicine from a pharmacist who gave polyclav 625 cheston total and nicip plus.     And once I'm back in Mumbai, I had this cough started again with difficulty in breathing. Cough is mostly dry and I get cold also mostly in the morning. I visited the doctor again and he advised to have okacet cold for 5-6 days and cobadex czs. Please advise.
