Dry itchy cough: This time of year, you are likely experiencing allergy symptoms. These symptoms can include clear mucus from the mouth or nose as well as possibly itchiness in the throat, nose and eyes. If you feel like you have to clear your throat often, you could also been experiencing a post nasal drip. Use of a nasal steroid like Flonase and an antihistamine like Allegra can help improve all your symptoms
