 What is the difference between a "cold" and a sinus infection?
A simple upper respiratory infection or "cold" is a viral illness that lasts for a
limited period of time; usually improving in five to seven days with or without treatment. If the symptoms are worsening instead of improving after that time, a sinus infection may be developing. Antibiotics may be needed to eliminate the infection.
 Do allergies play a role in sinus trouble?
Allergies sometimes cause swelling and blockage which can lead to sinus trouble. Therefore, the incidence of sinus infection among allergic patients is much higher than among non-allergic patients. Unfortunately, allergy treatment alone is not always succesful in resolving the sinus problem.
Colds and allergies can swell sinus linings and cause mucous to back up; leading to infection.
 What about asthma and sinus problems?
Knowledge of the relationship between the upper airway (nose and sinuses) and the lower airway (windpipe and lungs) is well-established. Upper airway infections frequently trigger lower airway problems such as asthma.
