If you have cold symtoms that last more than a week and even the over the counter medication for cold relief do not help, then it is not the common cold and one should seek medical advice without further delay.

The doctor can find out if the symptoms are due to an allergy or other conditions like Wegener's granulomatosis. Wegener's granulomatosis is treatable easily if diagnosed in early stages. If left untreated, it can have affect other organs like kidneys and may become fatal.

Normally common cold would cure itself in 5 to 7 days with no medication.
