Almost 8 days back I got cold. Have taken Cetirizine for 3 days and one cough syrup, took steam, gargled may times. Now cold is not there but Slightly morning cough is there and can feel bothersome mucus on chest and throat. Sometimes have to take long breath(not sure if is a breathing problem). Very frequently I am taking burps as well .Please let me know what can be the problem and how should I proceed.
