10 Causes of Sinus Infection
Cause #2: Allergies
Allergies are one of the possible sinus infection causes. Sinusitis due to an allergy is more common in early childhood due to exposure to animal dander, pollen, dust, and smoke. Those who have a family history for allergic sinusitis have a greater risk of suffering from it. It can be either acute or chronic. Acute allergic sinusitis lasts no longer than 4 weeks, while chronic allergic sinusitis lasts more than 8 weeks.
Allergic sinusitis signs and symptoms include nasal congestion, post nasal drip persisting for more than two weeks, itchy nose, throat, and eyes, sleep problems such as insomnia, reduced sense of smell and taste, headache, tenderness, and pressure and swelling around the forehead, cheeks, nose, and between the eyes.
