The symptoms of a cold with a runny nose generally recover within seven to ten days. A runny nose during a cold is usually caused by a viral infection. For viral colds, the condition of the patient is generally self-limiting. The natural course of the illness is usually seven to ten days, so the symptoms of a runny nose usually recover within this timeframe. However, for patients with a cold, there is often also a symptom of coughing. Although in most cases, the cough also eases within seven to ten days, some patients with colds may experience persistent coughing symptoms that can even last for one to two months. This condition is referred to as post-cold cough or post-infectious cough.
