I have had cold since couple of weeks, I have taken antiboitics the moment I had a feeling I am catching cold. I believe that suppressed the cold and since then I am coughing and some mucus is coming out. Now I have started taken cough syrup and from then my right ear is blocked. I can hear little from the blocked ear too and there is no pain.

I have a feeling mucus is still there inside and now it has blocked my ear. Please suggest what is the best remedy for this.

Thanks-
