What is Sinus Infection (Sinusitis)

Sinus Infection (Sinusitis) occurs when the tissues lining your sinuses, which are small air pockets located behind your forehead, nose, cheekbones, and eyes, become inflamed. Mucus builds up, which encourages bacteria and germs to grow in your sinus cavity, causing bacterial or viral infection. Excess mucus is common if you have a cold or allergies
