Bridge of Nose Throbbing in Freezing Air: Sphenopalatine Vasomotor Reflex vs. Ethmoid Sinusitis

If the bridge of nose aches in cold weather, especially when you breathe freezing air, the cause is often a temporary reaction of the nerves and blood vessels inside the nose. This can produce aching, pressure, stinging, or a throbbing feeling around the bridge of the nose and between the eyes.

However, similar discomfort can occur with inflammation or infection in the ethmoid sinuses, which sit behind the bridge of the nose. The timing, associated symptoms, and how long the pain lasts can help distinguish a cold-air response from ethmoid sinusitis.

This information is educational and cannot replace an examination. Speak to a doctor if symptoms are severe, persistent, worsening, or could represent anything serious or life threatening.

Why freezing air can cause a throbbing nose

The nose is highly sensitive to temperature changes. Cold air stimulates sensory nerves in the nasal lining, including branches of the trigeminal nerve. In response, the autonomic nervous system can alter blood flow and gland activity inside the nose.

One proposed mechanism is a sphenopalatine vasomotor reflex. The sphenopalatine ganglion is a group of nerve cells located deep behind the nasal cavity. It is involved in regulating blood vessel width and secretions in the nose and nearby areas. Cold stimulation may trigger:

• Temporary widening of blood vessels in the nasal lining
• Swelling of the nasal tissues
• Increased mucus production or a runny nose
• Stinging, aching, pressure, or throbbing around the bridge of the nose
• Headache or discomfort between the eyes

The term “sphenopalatine vasomotor reflex” describes a possible nerve-and-blood-vessel response; it is not usually a formal diagnosis made in a clinic. The symptoms are generally brief and improve after moving into warmer air.

Cold, dry air can also irritate the nasal lining and cause dryness or small cracks. This may lead to soreness, burning, crusting, or minor nosebleeds. People with allergies, nonallergic rhinitis, asthma, migraine, or a sensitive nasal lining may notice stronger reactions.

Features that favor a cold-air reflex

A cold-air response is more likely when the discomfort:

• Starts within minutes of exposure to freezing or very cold air
• Improves after warming up or going indoors
• Occurs without fever or feeling generally unwell
• Is accompanied by watery nasal discharge or temporary congestion
• Affects both sides or feels diffuse rather than focused on one area
• Does not continue for many hours after the exposure ends
• Happens repeatedly in similar weather conditions

The pain may feel like a dull throb, pressure, or sharp cold “ache.” It can sometimes resemble the pain caused by eating ice cream too quickly, although the location and mechanism are not identical.

What is ethmoid sinusitis?

The ethmoid sinuses are small air-filled spaces between the eyes and behind the upper part of the nose. Ethmoid sinusitis means inflammation of these sinuses. It can follow a viral upper respiratory infection, allergies, or, less commonly, a bacterial infection.

Inflammation in this area may cause pain or pressure at the bridge of the nose, between the eyes, or near the inner corners of the eyes. The discomfort may be worse when bending forward, coughing, or moving the head.

Ethmoid sinusitis becomes more likely when the symptoms are not limited to cold-air exposure and include several of the following:

• Nasal congestion that persists
• Thick or discolored nasal drainage
• Reduced sense of smell
• Pressure or pain between the eyes
• Facial tenderness
• Cough, particularly at night
• Fever or fatigue
• Symptoms lasting more than about 10 days without improvement
• Symptoms that improve and then become significantly worse

Most sinus infections begin as viral illnesses and improve without antibiotics. Clinical guidance from infectious disease and ear, nose, and throat organizations generally reserves antibiotics for patterns suggesting bacterial sinusitis, such as persistent symptoms without improvement, severe symptoms with high fever and purulent discharge for several days, or worsening after an initial improvement.

Discolored mucus by itself does not prove that a bacterial infection is present.

Comparing the two causes

Feature	Cold-air vasomotor response	Ethmoid sinusitis
Trigger	Freezing or dry air	Often follows a cold, allergy flare, or infection
Onset	Rapid, during exposure	Develops over hours or days
Duration	Usually improves with warmth	Persists or progressively worsens
Nasal discharge	Often watery	May be thick, though not always
Fever	Unusual	Possible, especially with more severe infection
Pain pattern	Brief aching, stinging, or throbbing	Ongoing pressure or tenderness between the eyes
General illness	Usually absent	Fatigue and feeling unwell may occur
Bending forward	Usually little effect	May increase pressure or pain

These distinctions are helpful but not absolute. A person can have nasal sensitivity and sinus inflammation at the same time.

What you can try at home

For discomfort triggered by freezing air:

• Cover your nose and mouth with a scarf or mask to warm inhaled air.
• Breathe through your nose gently when possible.
• Use a humidifier if indoor air is very dry, keeping it clean to prevent microbial growth.
• Consider saline nasal spray to reduce dryness and irritation.
• Avoid inserting cotton swabs or other objects into the nose.
• Warm your face gradually rather than applying very hot water or direct heat.

If congestion is present, saline irrigation may help some adults. Use sterile, distilled, or previously boiled and cooled water, and clean the irrigation device according to the manufacturer’s instructions.

Pain relievers such as acetaminophen or ibuprofen may help some people, provided they are safe for you. Follow the label directions. Ask a pharmacist or doctor before using decongestants if you have high blood pressure, heart disease, glaucoma, prostate problems, are pregnant, or take interacting medicines. Nasal decongestant sprays should generally not be used for more than three days unless a clinician advises otherwise, because overuse can cause rebound congestion.

If you are unsure whether your symptoms fit a cold-air reaction, allergy, migraine, or sinus problem, you might consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. It should support—not replace—medical care.

When to contact a doctor

Arrange medical advice if the bridge-of-nose pain:

• Continues after you are no longer exposed to cold
• Lasts more than several days or keeps returning
• Is accompanied by persistent congestion, facial pressure, or drainage
• Interferes with sleep or daily activities
• Keeps occurring without a clear cold-air trigger
• Follows an injury to the nose or face
• Occurs with frequent nosebleeds or sores inside the nose

A clinician can examine the nasal lining, check for infection or allergy, and assess whether the pain may be coming from migraine, nerve irritation, dental problems, or another source. Imaging is not usually needed for a short-lived cold-air response and is generally reserved for persistent, recurrent, complicated, or unclear cases.

Seek urgent medical care for warning signs

Although serious complications are uncommon, speak to a doctor urgently or seek emergency care if you develop:

• Swelling, redness, or severe pain around an eye
• Vision changes, double vision, or difficulty moving the eye
• Severe headache, stiff neck, confusion, fainting, or repeated vomiting
• High fever with rapidly worsening facial symptoms
• Marked swelling of the face
• Trouble breathing or swallowing
• A nose injury with uncontrolled bleeding or a visibly crooked nose
• Skin on the nose that becomes white, gray, waxy, numb, or blistered after extreme cold exposure

In most cases, a bridge-of-nose ache that appears only in freezing air and settles with warmth is more consistent with cold-induced nasal nerve and blood-vessel sensitivity than ethmoid sinusitis. Persistent symptoms, fever, ongoing discharge, or eye-related changes deserve medical assessment rather than being attributed to the weather alone.
