I have irritation in my chest which is itchy and it feels like something is sitting there. when i cough, nothing much is coming up from the chest. i visited a doctor 2 weeks ago he told me i had hay-fever - i got antibiotics, but this is not stoppin?

Itchy chest: If you had a recent viral upper respiratory tract infection and did some coughing, it's likely that your trachea had some irritation leading to a hacking,nonproductive cough. Taking a suppressant cough syrup like robitussinDM would sooth the discomfort. If you want to loosen mucus, take a syrup like mucinex. Your symptom could also be from irritants in the environment or excessive dryness.
