Recurring Cold Symptoms - going on 3 months!! I know there has been this awful virus floating around, but I have been struggling with nasal congestion, post nasal drip, and a constant cough.

Cold Symptoms. Runny nose, sore throat, and cough are a few common symptoms of a cold. These symptoms usually last from one to two weeks. Symptoms that last longer than this may be an indication of allergies rather than a cold. In rare cases, cold symptoms can lead to complications or to a more serious illness.
