Where Is Ethmoid Sinus Pain Located? Common Pain Areas

Ethmoid sinus pain is sometimes felt deep between or behind the eyes, along the bridge of the nose, and near the inner corners of the eyes. Because of where the ethmoid sinuses are situated in the skull, the discomfort can feel like a deep ache in the center of the face or around the eyes ^[1][2]. However, it is important to know that there is no reliable sinus-specific pain map, and pain location alone cannot diagnose ethmoid sinusitis ^[3].

Anatomy of the Ethmoid Sinuses

Unlike the maxillary (cheek) and frontal (forehead) sinuses, which are larger paired spaces, the ethmoid sinuses are made up of a honeycomb-like cluster of small air spaces called ethmoid air cells ^[1].

These air cells are located between the upper part of the nasal cavity and the inner walls of the eye sockets ^[1]. Because they sit directly behind the bridge of the nose and adjacent to the inner eye, inflammation in this area may be felt near the center of the upper face ^[1].

Common Pain Locations

When the ethmoid sinuses become inflamed, some people experience discomfort in specific areas, though many people with sinus disease have little or no facial pain ^[3]. Possible locations include:

• Between or behind the eyes: Some people report a deep pressure or aching between the eyes ^[1].
• Bridge of the nose: Discomfort may concentrate along the upper part of the nose ^[1].
• Inner corners of the eyes: Pain can occur at the inner corner of the eye, sometimes extending toward the tear duct area ^[4].
• Around the eyes: The pain can sometimes radiate outward, causing a generalized aching around the eye sockets ^[2].

Why Pain Location Is Not Enough

You cannot rely on pain location alone to pinpoint the source of a sinus problem. Research shows that in patients with chronic rhinosinusitis, the location of their facial pain does not reliably match the location of sinus inflammation seen on CT scans ^[3].

In fact, “chronic” sinusitis means inflammation (not always an active infection) that lasts for 12 weeks or more ^[5]. To accurately diagnose chronic ethmoidal sinusitis, doctors look for a combination of long-lasting symptoms—such as nasal congestion and/or thick nasal discharge, and sometimes a reduced sense of smell—along with objective evidence of inflammation ^[5][6]. This evidence is gathered using a nasal endoscopy (where a clinician uses a small camera to look inside the nasal passages) or a CT scan ^[5]. Imaging is generally used when symptoms persist for months, recur frequently, are atypical, or if complications are suspected ^[6].

Other conditions frequently mimic sinus pain. For example, in studies of people seeking care for a self-described “sinus headache,” most are actually experiencing a migraine ^[7]. Migraines can cause pain in the exact same areas of the face and even produce nasal symptoms like congestion or a runny nose ^[7]. Other potential causes include dental problems, jaw disorders, or nerve conditions like trigeminal neuralgia ^[8]. Pain triggered by chewing or temperature changes may point to a dental or jaw issue, while brief electric-shock-like pain suggests a nerve problem ^[9][8]. If your facial pain persists, you should arrange a routine clinical evaluation rather than assuming it is a sinus infection.

When to Seek Urgent or Emergency Care

Because the ethmoid air cells are separated from the eye sockets by only a paper-thin layer of bone, severe infections can spread into the orbit (the eye socket) ^[1].

Seek emergency medical evaluation (such as at an emergency room) if you experience:

• A bulging appearance of the eye ^[10]
• Double vision, reduced vision, or any visual changes ^[11][12]
• Pain when moving your eyes, or an inability to move them normally ^[10]
• Confusion, severe headache, neck stiffness, or repeated vomiting ^[13]

Contact a clinician promptly for a same-day urgent assessment if you develop:

• New swelling or redness of the eyelids or the area around the eyes ^[10]
• A significant fever alongside your facial pain ^[10]
