Sinusitis | A respiratory disorder | causes, symptoms and treatment

A bad cold is often mistaken for a sinus infection. Many symptoms are the same, including headache or facial pain, runny nose and nasal congestion.
Sinusitis is an inflammation of the sinuses. It is often caused by bacterial (germ) infection. Sometimes, viruses and fungi (molds) cause it. People with weak immune systems are more likely to develop bacterial or fungal sinus infection. Some people with allergies can have "allergic fungal sinus infection." Acute sinus infection lasts three to eight weeks. A sinus infection lasting longer than eight weeks is considered chronic.
The sinuses are small air pockets located behind your forehead, nose, cheekbones, and in between the eyes.
Normal sinuses are lined with a thin layer of mucus that traps dust, germs and other particles in the air. Tiny hair-like projections in the sinuses sweep the mucus (and whatever is trapped in it) towards openings that lead to the back of the throat. From there, it slides down to the stomach. This continual process is a normal body function.
Healthy sinuses are filled with air. But when they become blocked and filled with fluid, germs can grow and cause an infection.
Conditions that can cause sinus blockage include:
• The common cold
• Allergic rhinitis, which is swelling of the lining of the nose
• Small growths in the lining of the nose called nasal polyps
• A deviated septum, which is a shift in the nasal cavity
The symptoms of sinusitis are similar to those of a common cold. They may include:
• a decreased sense of smell
• fever
• stuffy or runny nose
• headache from sinus pressure
• fatigue
• cough
Types
You may hear your doctor use these terms:
• Acute sinusitis usually starts with coldlike symptoms such as a runny, stuffy nose and facial pain. It may start suddenly and last 2-4 weeks.
• Subacute sinus inflammation usually lasts 4 to 12 weeks.
• Chronic inflammation symptoms last 12 weeks or longer.
• Recurrent sinusitis happens several times a year.
