Can a Migraine Cause a Fever?

Introduction: Can a Migraine Cause a Fever?

Migraines are intense headaches characterized by severe throbbing pain, often accompanied by additional symptoms like nausea, sensitivity to light and sound, and visual disturbances. On the other hand, a fever is commonly associated with infections or immune system responses. But can a migraine actually cause a fever? In this blog post, we will explore the relationship between migraines and fever, addressing the misconceptions and shedding light on the facts. By the end, you will have a better understanding of whether migraines can truly cause a fever.

Understanding Migraines:

Migraines are neurovascular disorders that involve complex changes in the brain and blood vessels. The exact cause of migraines is not fully understood, but various factors, including genetics, environmental triggers, hormonal changes, and neurotransmitter imbalances, are thought to play a role.

Fever and Its Causes:

A fever is defined as an increase in body temperature above the normal range, typically as a response to an infection or inflammation. Common causes of fever include viral or bacterial infections, autoimmune disorders, certain medications, or reactions to certain vaccines. Fever is generally accompanied by other symptoms such as chills, sweating, fatigue, and body aches.

The Connection between Migraines and Fever:

While migraines can be associated with several symptoms that may resemble fever-like sensations, it is important to differentiate between the two. Migraines themselves do not typically cause an actual increase in body temperature that qualifies as a fever.

Migraine-Associated Symptoms:

During a migraine attack, individuals may experience symptoms that resemble fever-related sensations. These can include feeling hot or flushed, experiencing perspiration or clamminess, and even feeling cold or chilled. However, these symptoms are associated with the migraine episode itself and do not necessarily indicate an elevated body temperature.

Fever as a Migraine Trigger:

It is worth mentioning that fever can sometimes trigger migraines in susceptible individuals. Inflammatory processes associated with fever may potentially cascade into a migraine attack in those already prone to migraines. However, this does not mean that the migraine itself causes the fever; rather, the fever acts as a trigger for the migraine.

Infections, Illnesses, and Migraines:

In some cases, migraines can be triggered by certain infections or illnesses that are accompanied by fever, such as the flu or sinusitis. The fever associated with these conditions can exacerbate the susceptibility to migraines in individuals who are already prone to them, leading to increased migraine frequency or intensity.

Differentiating between Migraines and Fever:

To determine whether you have a migraine or a condition associated with fever, it is important to assess the presence of other symptoms characteristic of infections or illnesses. If you experience symptoms like sore throat, cough, runny nose, body aches, or fatigue in addition to headache, it is more likely that you are dealing with an illness that has caused a fever, rather than a standalone migraine episode.

When to Seek Medical Attention:

If you are experiencing symptoms of fever alongside a severe headache, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment. They can evaluate your symptoms, perform a physical examination, and order any necessary tests to rule out underlying infections or conditions that may require medical intervention.

Treatment and Management of Migraines and Fever:

Treatment approaches for migraines and fever differ based on their respective causes. For migraines, various strategies, including over-the-counter pain relievers, prescription medications, lifestyle modifications, stress management techniques, and identifying and avoiding trigger factors, can be effective in managing and reducing the frequency of migraines. Fever caused by infections or other underlying conditions may require specific medical interventions, such as antibiotics, antiviral medications, or anti-inflammatory drugs.


While migraines can be associated with symptoms that resemble fever-like sensations, migraines themselves do not typically cause an actual fever. It is essential to differentiate between the two and understand the underlying causes of each. Migraines can be triggered by fever-inducing factors, but it is the fever that serves as a trigger, not the other way around.

If you are unsure whether your symptoms indicate a migraine or are associated with an underlying illness, it is crucial to consult with a healthcare professional for an accurate diagnosis. They can provide appropriate guidance and determine the best course of management tailored to your specific situation.
