Overview

Sinus headaches are headaches caused by inflammation or congestion in the sinuses, which are air-filled spaces around the nose and eyes. They are often associated with sinus infections, allergies, or colds that block normal sinus drainage. The pressure buildup in the sinuses leads to pain and discomfort, typically felt in the face and head. Sinus headaches are commonly mistaken for migraines, but their causes and features differ.

Symptoms

Symptoms of sinus headaches usually occur along with signs of sinus congestion or infection.

  • Deep, constant pain in the forehead, cheeks, or around the eyes

  • Pain that worsens when bending forward or lying down

  • Nasal congestion or blocked nose

  • Thick nasal discharge

  • Facial tenderness or swelling

  • Reduced sense of smell

  • Fever or fatigue in cases of infection

Causes

Sinus headaches are caused by inflammation of the sinus lining, which prevents normal mucus drainage. This inflammation may result from viral or bacterial sinus infections, allergic reactions, or upper respiratory infections such as the common cold. When the sinuses become blocked, pressure builds up and leads to headache pain.

Risk Factors

Several factors increase the likelihood of developing sinus headaches.

  • Recurrent sinus infections

  • Seasonal or environmental allergies

  • Deviated nasal septum or nasal polyps

  • Smoking or exposure to air pollution

  • Recent upper respiratory infections

Complications

If the underlying sinus condition is not treated, sinus headaches may become recurrent or chronic. Ongoing sinus inflammation can lead to chronic sinusitis, which causes persistent facial pain, nasal congestion, and reduced quality of life. In rare cases, severe infections can spread to nearby structures such as the eyes or brain.

Prevention

Prevention focuses on keeping the sinuses clear and reducing inflammation. Managing allergies, avoiding known triggers, and maintaining good nasal hygiene can help. Staying hydrated and treating colds promptly reduce the risk of sinus blockage. Seeking medical care for persistent nasal congestion or facial pain helps prevent recurrent sinus headaches and related complications.
