I have been having cough and cold for past 8 to 10 days. I am... 136 cm height, Indian male, 26 years of age. Initially, it started with light cough, but now it has progressed significantly, and I have the thick mucus build-up, and because of that, it-- I had started to have pain below my eye areas or right side of the eye, especially when I cough or sneeze. What are the medicines that I should start taking to improve this quickly?
