Hello Doctor, I am having cold with my right nose blocked with pain towards right side of the face, right eye, right side of forehead and right jaw. Couple of days back I had a bad cough too but that was relieved with Cheston cold 1 tab for 4 days. Yesterday I felt feverish and bodyache also so started with Cheston again. Please suggest me , may be I am not taking correct dosage of Cheston? Regards, Ratna.
