A cold sometimes develops into sinusitis. This is a condition in which the sinuses, or air passages, behind the face become swollen.

A cold usually lasts about one to two weeks and goes away on its own. But sinusitis can last three weeks or longer. In fact, it can become chronic, dragging on for months or even years.

Signs of sinusitis may include cold-like symptoms, such as a sore throat and congestion. Other signs may include:

face pain or pressure
pain in upper teeth
weakness and fatigue
green or yellow nasal discharge.

Your doctor can recommend the best treatment. Over-the-counter (OTC) and prescription remedies may provide relief. Oral decongestants and decongestant nasal sprays can reduce congestion. But don't use decongestant nasal sprays for more than three days. Longer use can actually worsen congestion. OTC saline nose sprays are safe and can provide relief.

Sometimes sinusitis is caused by a bacterial infection. If this is the case, your doctor can prescribe antibiotics that will help clear up the infection.

Inhaling steam from a cup of boiled water or a vaporizer can lessen discomfort. Applying a warm, moist washcloth to the cheekbone and eye area can also provide relief.
