Can a Deviated Septum Cause Headaches—or Is Something Else More Likely?

Can a Deviated Septum Cause Headaches?

A deviated septum is not typically considered a direct cause of recurring headaches. Instead, it may be one part of a broader nasal or sinus problem.

The septum is the wall of cartilage and bone that separates the two sides of the nose. When it is significantly off-center, one nasal passage may become narrower than the other. This can make breathing through the nose more difficult, especially when allergies, a respiratory infection, or another source of inflammation causes additional swelling.

A deviated septum may occur alongside chronic congestion, sinus inflammation, enlarged turbinates, or other conditions that contribute to facial pressure. However, the presence of a deviated septum does not necessarily mean it is responsible for a person’s headaches.

Many people have mild septal deviations without experiencing symptoms at all.

How Can a Deviated Septum Affect Nasal Breathing?

The most common effect of a deviated septum is restricted airflow through one or both sides of the nose. Symptoms may include:

• One nostril consistently feeling more blocked than the other
• Difficulty breathing through the nose
• Mouth breathing, particularly during sleep
• Nasal congestion that becomes worse during colds or allergy flares
• Frequent nosebleeds caused by dryness
• Noisy breathing or disrupted sleep

According to the Mayo Clinic, many deviated septums cause no symptoms. When symptoms do occur, nasal obstruction is generally the primary concern.

If headaches are also present, an evaluation can help determine whether the symptoms are connected or whether another headache condition is more likely.

What Does a “Sinus Headache” Feel Like?

“Sinus headache” is a common term used to describe pain or pressure around the forehead, cheeks, eyes, or bridge of the nose. However, it is not a specific medical diagnosis.

Headaches associated with acute sinus inflammation generally occur with other nasal or infectious symptoms. These may include:

• Significant nasal congestion
• Thick or discolored nasal drainage
• Reduced sense of smell
• Facial pain or tenderness
• Fever
• Symptoms that worsen after initially improving

Facial pressure without substantial nasal symptoms may be more consistent with migraine, tension headache, temporomandibular joint dysfunction, or another source of pain.

The American Academy of Otolaryngology–Head and Neck Surgery notes that migraine and tension headaches are commonly mistaken for sinus headaches. Pain in the sinus area does not automatically mean that a sinus condition is responsible.

Could the Headache Actually Be a Migraine?

Migraine is one of the most common conditions mistaken for a sinus headache. Migraine can produce facial pressure and nasal symptoms because it affects nerves that extend through the forehead, cheeks, and jaw.

Migraine symptoms may include:

• Pain or pressure around the forehead or eyes
• Nasal congestion or a runny nose
• Sensitivity to light, sound, or odors
• Nausea or vomiting
• Dizziness
• Moderate to severe pain
• Pain that worsens with routine physical activity
• Headaches that occur repeatedly or follow a recognizable pattern

Because migraine and sinus conditions can produce overlapping symptoms, treating nasal congestion alone may not resolve the headache when migraine is the underlying cause.

A primary care provider or neurologist may need to participate in the evaluation when the symptoms are more consistent with a headache disorder than a nasal or sinus condition.

What Other Conditions Can Cause Headaches and Congestion?

A deviated septum is only one possible explanation for impaired nasal breathing. Several conditions can cause congestion, facial pressure, and headache symptoms.

Chronic sinusitis

Chronic sinusitis involves persistent inflammation of the nasal and sinus passages. Common symptoms include nasal obstruction, drainage, facial pressure, and reduced smell.

Some patients also report headaches, but headache alone does not establish chronic sinusitis as the cause. Symptoms generally need to persist for at least 12 weeks, and an examination or imaging may be needed to confirm inflammation.

Allergic rhinitis

Seasonal and year-round allergies can cause swelling, itching, sneezing, clear drainage, and nasal congestion. Headaches may occur at the same time, but an evaluation may be needed to determine whether allergies, migraine, or another condition is responsible.

Nasal polyps

Nasal polyps are soft, noncancerous growths associated with chronic inflammation inside the nose and sinuses. They may contribute to nasal obstruction, reduced smell, drainage problems, and chronic sinus symptoms.

When headaches are also present, the full pattern of symptoms should be evaluated rather than assuming the polyps are the cause.

Enlarged turbinates

Turbinates are structures inside the nose that warm, filter, and humidify inhaled air. Allergies, irritation, and other sources of inflammation can cause them to swell and narrow the nasal passages.

Tension headaches or TMJ disorders

Muscle tension, teeth grinding, jaw-joint problems, and neck strain may cause pain around the temples, forehead, cheeks, or ears. These symptoms can sometimes be mistaken for sinus pressure.

When Might a Headache Be Related to a Nasal or Sinus Condition?

A nasal or sinus condition may warrant consideration when headaches occur alongside symptoms such as:

• Persistent nasal congestion
• Thick nasal drainage
• Reduced sense of smell
• Facial tenderness or pressure
• Fever
• Repeated episodes of clinically diagnosed sinusitis
• Symptoms that worsen after initially improving

These symptoms can still overlap with migraine and other headache disorders. A symptom pattern alone cannot confirm the cause.

When headaches occur without meaningful nasal symptoms—or are accompanied by nausea, light sensitivity, sound sensitivity, or a recurring pattern—migraine or another headache disorder may be more likely.

How Does an ENT Evaluate Headaches and Nasal Obstruction?

An ENT evaluation focuses on whether there is objective evidence that a nasal or sinus condition may be contributing to the symptoms.

Your provider may ask:

• Where the pain occurs
• How frequently the headaches develop
• How long each episode lasts
• Whether nasal symptoms occur at the same time
• Whether light, sound, activity, or certain triggers make the pain worse
• Whether previous sinus or headache treatments have helped

A nasal examination may identify a deviated septum, enlarged turbinates, nasal polyps, drainage, or signs of inflammation.

If the examination and symptom history raise concern for chronic or complicated sinus disease, imaging may be considered. Imaging is not necessary for every patient with headache or nasal congestion.

Can Septoplasty Improve Headaches?

Septoplasty is designed to improve nasal airflow when a deviated septum is causing meaningful obstruction. It is not considered a general treatment for migraine, tension headache, or facial pain without evidence that nasal obstruction is contributing.

Some appropriately selected patients may notice an improvement in associated pressure or discomfort after treatment, but headache relief is not guaranteed. If migraine or another headache disorder is suspected, evaluation by a primary care provider or neurologist may also be appropriate.

An ENT specialist can determine whether septal deviation is significantly affecting nasal airflow and whether septoplasty may be appropriate based on the examination, symptoms, and response to previous treatment.

Treatment Depends on the Underlying Cause

There is no single treatment for headaches that occur with nasal congestion. The appropriate approach depends on what is causing each symptom.

Treatment may focus on:

• Managing allergy-related inflammation
• Addressing acute or chronic sinusitis
• Improving nasal airflow
• Treating enlarged turbinates or nasal polyps
• Correcting a significantly deviated septum
• Evaluating migraine, tension headache, or another neurological condition

The goal is to identify the underlying cause instead of assuming that every headache near the forehead or cheeks is sinus-related.

When Should You Schedule an Evaluation?

Consider scheduling an evaluation if:

• One side of your nose remains consistently blocked
• Congestion lasts for several weeks
• Headaches repeatedly occur with significant nasal symptoms
• You experience recurring sinus infections
• Your sense of smell has decreased
• Symptoms interfere with sleep, exercise, or daily activities
• Over-the-counter treatments are not providing adequate relief

A combined assessment of the headaches and nasal symptoms can help determine whether they are connected.

When Does a Headache Need Prompt Medical Attention?

Seek prompt medical care for:

• A sudden or unusually severe headache
• Weakness, numbness, confusion, fainting, or difficulty speaking
• New or significant vision changes
• High fever or a stiff neck
• Persistent vomiting
• Swelling or redness around the eyes
• A headache that develops after a head injury
• A new headache that is rapidly worsening

These symptoms may require urgent evaluation and should not be assumed to result from a deviated septum or sinus problem.

Don’t Assume Every Headache Is a Sinus Headache

A deviated septum can make nasal breathing more difficult, but it is not always the reason a headache develops. Sinus inflammation, allergies, nasal polyps, migraine, tension headache, TMJ dysfunction, and other conditions can produce overlapping symptoms.
