The primary difference between a sinus infection and a cold is its duration. While colds generally peak after two to three days, sinus infections can last seven days or more. Further, people who simply have a common cold generally do not run a fever or experience significant fatigue, while people suffering from sinus infections may suffer both.
The small opening from the sinuses to the nose can become blocked, which leads to a build-up of pressure inside the sinuses. This is known as sinusitis. For some people with sinusitis, the pressure builds up to such an extent that it causes pain, or a sinus headache. You may feel stuffy and congested for a while, but it normally gets better once the cold goes away. Sinusitis and sinus headaches can last much longer.
