Inflammation in the sinuses is called sinusitis. This can cause the sinuses to become blocked and the nose to fill with fluid. This problem is usually caused by a cold or allergy. When the fluid in the nose increases, bacteria also start growing and can cause infection (bacterial sinusitis). This condition can be quite serious. Nasal congestion, headache, runny nose and severe pain in half the head are symptoms of sinus. The condition of sinus can be painful for the person and affect the routine. Apart from this, sinus can also affect the sex life of a person to some extent.
