Headaches are one of the most common forms of pain and a primary reason for absenteeism from work or school and medical visits. Headaches can generally be divided into two main categories: primary headaches and secondary headaches. Each differs in its causes, methods of diagnosis, and management.

## Understanding Primary Headaches

A primary headache is a type of headache that occurs on its own; it is not a symptom of another medical condition. The primary headache is the underlying health issue itself. The main types of primary headaches include [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>):

- **Tension headache:** This is the most common type of headache. It is often described as a constant mild to moderate pressure on the face, head, or neck, and the person may feel as if there is a band tightening around their head. It usually affects both sides of the head and can last from 30 minutes to 7 days. It is often associated with emotional stress, lack of sleep, mental fatigue, and dehydration [\[1\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S1>) [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>).

- **Migraine:** This is characterized by recurring episodes of moderate to severe pain, usually pulsating and affecting one side of the head. It may be accompanied by nausea, vomiting, or increased sensitivity to light or sound [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>).

- **Cluster headache:** This is a rare but extremely painful type of headache that usually occurs on one side of the head, often around or behind the eye. It may be accompanied by redness of the eye, eyelid swelling, or nasal congestion or runny nose on the same side. Attacks last from 15 minutes to 3 hours and occur almost daily for weeks or months, separated by pain-free periods [\[3\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S3>).

## Understanding Secondary Headaches

A secondary headache is a symptom of another underlying medical condition that compresses, pulls, or pushes on pain-sensitive nerve endings. These conditions affect the brain or the surrounding areas. It is important to identify and treat the underlying cause of a secondary headache. Some causes of secondary headaches include [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>):

- Cerebrovascular disorders, including stroke.

- Brain tumors.

- Brain injuries.

- High blood pressure.

- Infections.

- Substance abuse or withdrawal.

- Routine changes such as air travel or fasting.

## When to See a Doctor?

Not all types of headaches require a doctor's visit; most can be relieved by lifestyle changes or over-the-counter pain relievers [\[1\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S1>). However, a headache can sometimes be a warning sign of a more serious health problem that requires immediate medical attention. You should seek urgent medical help if you experience any of the following symptoms [\[1\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S1>) [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>):

- A sudden and severe headache, possibly with a stiff neck.

- A severe headache accompanied by fever, nausea, or vomiting that is not related to another illness.

- A headache accompanied by confusion, weakness, double vision, or loss of consciousness, especially if these symptoms are new.

- A headache that worsens over days or weeks, or changes its pattern.

- A headache that occurs after a head injury.

- A headache accompanied by loss of sensation or weakness in any part of the body, as it could be a sign of a stroke.

- A headache with seizures or difficulty breathing.

- If you suffer from a persistent headache and have never had one before, especially if you are over the age of 50.

## Diagnosis and Treatment

To diagnose the potential cause of a headache, the doctor will review your medical history and headache history, and conduct physical and neurological examinations. The doctor may order laboratory tests or imaging studies such as a CT scan or MRI to rule out secondary causes [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>). It is helpful to keep a headache diary to record the time of occurrence, intensity, duration, any potential triggers, medications taken, sleep patterns, stress levels, and food and drink consumed [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>).

Headache treatment depends on its type and cause. For primary headaches, treatment may include lifestyle changes, relaxation techniques, and pain relievers. In cases of migraine or cluster headaches, doctors may prescribe specific medications such as triptans, steroids, or pure oxygen [\[3\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S3>). As for secondary headaches, treatment focuses on addressing the underlying medical condition causing them [\[2\]](<https://clinicsjo.com/en/faq/primary-vs-secondary-headache-differences-causes-and-when-to-seek-medical-help#source-S2>).
