Severe Headaches? Why Your Brain Is Pressing Down: Medically Approved Chiari Malformation Next Steps

Severe headaches can be frightening—especially when they keep coming back or worsen with coughing, sneezing, or straining. In some cases, these headaches are linked to a structural condition called chiari malformation.

If you've been told you may have a chiari malformation—or you're researching symptoms—this guide explains what it means, how it's diagnosed, and what medically approved next steps look like.

What Is Chiari Malformation?

Chiari malformation is a condition where part of the brain, called the cerebellum, extends downward into the spinal canal. Normally, the cerebellum sits fully inside the skull. In chiari malformation, there isn't enough space at the base of the skull, causing brain tissue to press downward through an opening called the foramen magnum.

This pressure can interfere with the normal flow of cerebrospinal fluid (CSF), which cushions and protects the brain and spinal cord.

There are different types, but the most common is:

• Chiari Malformation Type I – Often diagnosed in adolescence or adulthood. Symptoms may develop gradually.

More severe types are usually identified in infancy and are much rarer.

Why Does Chiari Malformation Cause Severe Headaches?

Headaches related to chiari malformation often have specific features:

• Pain at the back of the head
• Worsening with coughing, sneezing, or straining
• Brief but intense episodes
• Pressure-like sensation

The headache happens because:

• Brain tissue is compressed
• Cerebrospinal fluid flow is disrupted
• Pressure builds in sensitive areas at the base of the skull

Not all headaches are caused by chiari malformation. Migraines, tension headaches, dehydration, infections, and other neurological conditions are more common causes. That's why proper evaluation matters.

Other Symptoms of Chiari Malformation

While headaches are common, chiari malformation can affect more than just your head. Symptoms vary from mild to more serious.

Possible signs include:

• Neck pain
• Dizziness or balance problems
• Muscle weakness
• Numbness or tingling in hands or feet
• Trouble swallowing
• Ringing in the ears
• Vision problems (blurred or double vision)
• Poor coordination
• Sleep apnea

In some people, symptoms are mild and stable. In others, they can slowly worsen over time.

A related complication called syringomyelia may occur. This happens when a fluid-filled cyst forms within the spinal cord due to blocked CSF flow. It can cause:

• Loss of temperature sensation
• Muscle wasting
• Chronic pain
• Progressive weakness

This is why ongoing monitoring is important.

How Is Chiari Malformation Diagnosed?

The gold standard for diagnosing chiari malformation is an MRI scan of the brain and upper spinal cord.

Your doctor may recommend imaging if:

• You have headaches triggered by coughing or straining
• You have unexplained neurological symptoms
• Symptoms are progressive
• You have signs of spinal cord involvement

An MRI can show:

• How far the cerebellum extends downward
• Whether spinal fluid flow is blocked
• If syringomyelia is present

Sometimes, chiari malformation is discovered incidentally—meaning it's found during a scan done for another reason. Not everyone with imaging findings has symptoms.

That's an important point: treatment decisions are based on symptoms, not just MRI results.

When Is Chiari Malformation Serious?

It's important not to panic—but also not to ignore red flags.

Seek urgent medical care if you experience:

• Sudden, severe headache unlike any before
• Loss of consciousness
• Rapid weakness or paralysis
• Difficulty breathing
• Severe trouble swallowing
• New loss of bladder or bowel control

These could signal serious complications and require immediate evaluation.

In most cases, chiari malformation Type I progresses slowly, and many people manage it with monitoring and symptom control.

Medically Approved Next Steps

If chiari malformation is suspected or confirmed, here are evidence-based next steps:

1. See a Neurologist or Neurosurgeon

Specialists can:

• Confirm the diagnosis
• Assess symptom severity
• Evaluate for spinal cord involvement
• Recommend monitoring or treatment

2. Monitor Symptoms

If symptoms are mild, doctors may recommend:

• Periodic neurological exams
• Follow-up MRIs
• Tracking headache frequency and severity

Not everyone needs surgery.

3. Pain Management

For headache control, your doctor may suggest:

• Anti-inflammatory medications
• Migraine therapies (if overlapping features exist)
• Muscle relaxants
• Lifestyle modifications

Avoid heavy straining if it triggers symptoms.

4. Surgical Treatment (If Needed)

Surgery is considered when:

• Symptoms are severe
• Neurological deficits are worsening
• Syringomyelia is present
• Quality of life is significantly affected

The most common procedure is posterior fossa decompression surgery. This involves removing a small section of bone at the back of the skull to create more space and restore normal CSF flow.

Surgery can significantly improve symptoms in appropriate candidates—but like any operation, it carries risks. A detailed discussion with a neurosurgeon is essential.

Living With Chiari Malformation

Many people with chiari malformation live full, active lives—especially when symptoms are mild or well managed.

Helpful lifestyle steps include:

• Avoiding heavy straining or lifting
• Maintaining good posture
• Staying hydrated
• Getting consistent sleep
• Managing stress
• Following up regularly with your care team

If you have balance issues, physical therapy may help improve coordination and strength.

If anxiety develops due to chronic symptoms, mental health support can also be valuable. Chronic headaches are not "just in your head"—they are physically real and deserve proper care.

What Causes Chiari Malformation?

Most cases of chiari malformation Type I are congenital, meaning present at birth. It may develop due to:

• A small or misshapen skull
• Structural development differences
• Genetic factors

Less commonly, it can develop later in life due to:

• Trauma
• Infection
• Tumors
• Excess spinal fluid drainage

Your doctor will help determine which category applies to you.

The Bottom Line

Chiari malformation is a structural condition where brain tissue presses downward into the spinal canal. It can cause severe headaches—especially at the back of the head and triggered by coughing or straining.

Key points to remember:

• Not all severe headaches are chiari malformation.
• MRI is required for diagnosis.
• Treatment depends on symptoms—not just imaging.
• Many cases are mild and monitored.
• Surgery is reserved for more serious or progressive cases.
• Red flag symptoms require urgent medical attention.

If you're experiencing severe or unusual headaches, don't ignore them. Start by using Ubie's free AI-powered Headache symptom checker to help identify potential causes and prepare informed questions for your healthcare provider.

Most importantly, speak to a doctor about any headache that is severe, worsening, or accompanied by neurological symptoms. Some causes can be life threatening or require urgent treatment. Getting evaluated early is the safest step.

Severe headaches deserve answers—and with proper evaluation, chiari malformation can be identified and managed appropriately.
