Nasal congestion caused by sinusitis requires symptomatic anti-inflammatory treatment as the initial step, because sinusitis, which includes inflammation of the paranasal sinuses, is caused by acute inflammatory irritation leading to nasal symptoms. This condition can result in nasal congestion due to the repeated stimulation of the nasal conchae by yellow purulent secretions. Additionally, patients may experience discharge of yellow purulent material from the nasal cavity, facial swelling and pain, headaches, and fever among other symptoms. Examination with an endoscope may reveal bilateral congested and swollen nasal mucosa, and yellow purulent secretions in the nasal passages. Treatment initially requires symptomatic anti-inflammatory measures to reduce inflammation. Since it is a bacterial infection, patients can use antibiotics. Also necessary is the use of saline nasal irrigation and nebulized inhalations to contract the nasal conchae and alleviate congestion. Once the inflammation is reduced, nasal congestion will gradually improve. (The use of medications should be under the guidance of a doctor.)
