Any top respiratory infection can end up affecting your sinuses (air-filled cavities close to the nose and eyes). During the acute phase, the patient normally complains of thick nasal discharge, nasal obstruction, throat pain, postnasal drip, and heaviness of the head with kindness around the eyes and cheek. Most of the times these symptoms can be treated with medicines and nasal washes. However, if the symptoms happen again and again over a span of time with at least a few of the symptoms explained, then your ENT Specialist may recommend investigations, such as a CT scan of your sinuses.
