What are the symptoms of sinusitis

Sinusitis is a relatively common type of rhinitis, which causes great harm to patients in their lives and work. It often causes patients to have symptoms of nasal congestion.

Severe patients will suffer from memory loss, physical fatigue and other symptoms.

1. Blocked nose

The most prominent symptom of sinusitis is nasal congestion, which is mainly caused by edema of the nasal mucosa and nasal secretions filling the nasal cavity. Generally speaking, the severity depends on the patient's physical condition and condition. When nasal polyps appear, the nose will be completely blocked.

In addition to causing pain in the nose, sinusitis can also cause headaches in patients. This condition is more obvious during the day and is often manifested as sudden severe pain in the head or a heaviness in the head.

3. Runny nose

Purulent nasal discharge is another characteristic symptom of sinusitis. The amount of nasal discharge may be more or less, and the color is mostly yellow or yellow-green. Most of the nasal discharge flows into the pharynx due to the blockage of the nasal cavity.

Sinusitis is caused by reduced overall body resistance, such as excessive fatigue, cold and dampness, malnutrition, vitamin deficiency, and poor living environment.
