Sinusitis can be categorized into acute sinusitis,
lasting for days or weeks, or chronic sinusitis with longer-lasting symptoms. Acute sinusitis
usually occurs after a cold, which causes swelling in the lining of the nose, and this blocks
the sinus’ draining, causing symptoms of pain, throb, headache, sometimes a bad smell in the nose and bad taste, and coloured nasal discharge. Chronic sinusitis has longer-lasting symptoms of nasal congestion, catarrh, cough, lethargy,
headaches, and pressure, which is usually in the forehead, between the eyes or in the
cheeks. These symptoms can have significant effect on quality of life. Individually, symptoms
do not sound so serious, but the cumulative effect has a big effect on the quality of
life, productivity at work, sleep quality, and effect on relationships as well.
So the effect is quite significant.
