Migraines: Symptoms, Triggers, and Management

Migraines: Symptoms, Triggers, and Management

Migraines are more than just severe headaches, they're a complex neurological condition that can significantly impact your quality of life. If you've ever experienced a migraine, you know how debilitating they can be. In light of Migraine Awareness Week (September 1st-7th), this blog will delve into what migraines are, their symptoms, triggers, and how to manage them effectively.

Migraines are a neurological condition that causes recurring headaches and a range of other symptoms, including nausea, vomiting and sensitivity to light or sound. They can interfere with work, daily activities and overall quality of life, but understanding your triggers and treatment options can help reduce the frequency and severity of attacks.

What is a Migraine?

A migraine is a type of headache disorder characterised by intense, throbbing pain, usually on one side of the head. Unlike regular headaches, migraines often come with a host of other symptoms, such as nausea, vomiting, and sensitivity to light and sound. Migraines can last for hours or even days, making it difficult to carry out daily activities.

What Causes Migraines?

Although the exact cause of migraines isn't fully understood, they are thought to result from a combination of genetics, changes in brain activity and environmental factors. During a migraine, changes in nerve signalling and brain chemicals can affect pain pathways, leading to the characteristic headache and associated symptoms.

People with a family history of migraines are more likely to develop the condition. While the underlying cause cannot always be prevented, recognising personal triggers can help reduce the frequency of attacks.

Symptoms of a Migraine

The symptoms of a migraine can vary from person to person, but common signs include:

  • Severe Headache: Often localised to one side of the head, though it can occur on both sides.
  • Nausea and Vomiting: Many people experience an upset stomach and may vomit during a migraine.
  • Sensitivity to Light and Sound: Bright lights and loud noises can exacerbate the pain.
  • Visual Disturbances: Some people see flashing lights, zigzag patterns, or experience temporary loss of vision, known as an aura.
  • Dizziness: A feeling of lightheadedness or unsteadiness is common.

You may also experience:These symptoms don't occur in everyone, but they are recognised features of migraine attacks.

  • Neck pain or stiffness
  • Fatigue or low energy
  • Difficulty concentrating ("brain fog")
  • Sensitivity to smells
  • Tingling or numbness in the face or hands
  • Difficulty speaking
  • Blurred vision
  • Feeling exhausted after the migraine has resolved

What Does a Migraine Feel Like?

Migraine pain is often described as a throbbing or pulsating headache, usually affecting one side of the head, although it can occur on both sides. Unlike a typical headache, migraines are frequently accompanied by nausea, vomiting and increased sensitivity to light, sound or strong smells.

Many people find that everyday activities, such as walking upstairs or exercising, make the pain worse. During an attack, resting in a quiet, dark room often provides some relief.

What Triggers Migraines?

Migraines can be triggered by a variety of factors. Understanding your triggers is crucial to managing the condition. Common migraine triggers include:

  • Stress: Emotional stress is a major trigger for many people.
  • Hormonal Changes: Fluctuations in hormones, especially during menstruation, pregnancy, or menopause, can trigger migraines.
  • Dietary Factors: Certain foods and drinks, such as aged cheeses, processed meats, and alcohol (particularly red wine), are known triggers.
  • Sleep Patterns: Both lack of sleep and excessive sleep can trigger migraines.
  • Environmental Factors: Bright lights, strong smells, and sudden changes in weather can also bring on migraines.
  • Caffeine: While small amounts may help, excessive caffeine intake or withdrawal can trigger migraines.

Migraine vs Headache

Migraines and headaches are often confused, but they are different conditions with distinct symptoms.

Migraine Headache
Moderate to severe throbbing pain Mild to moderate dull ache
Usually affects one side of the head Often affects both sides
Nausea and vomiting are common Usually absent
Sensitive to light and sound Less common
Lasts 4–72 hours Often resolves within a few hours
May include aura Aura does not occur

If your headaches are frequent, severe or affecting your daily life, it's important to seek medical advice for an accurate diagnosis.

How Do I Know It's a Migraine?

Distinguishing a migraine from a regular headache is important for proper treatment. Here are some signs that what you're experiencing might be a migraine:

  • Intensity of Pain: Migraine pain is often more severe and pulsating compared to regular headaches.
  • Duration: Migraines can last from 4 hours to 72 hours if untreated.
  • Accompanying Symptoms: Unlike regular headaches, migraines are often accompanied by nausea, vomiting, and sensitivity to light and sound.
  • Aura: About 25-30% of people with migraines experience auras visual or sensory disturbances that occur before the headache phase.

What Are the 4 Stages of a Migraine?

Migraines typically progress through four stages, although not everyone experiences all stages:

  1. Prodrome: This early warning phase can start hours or even days before the headache. Symptoms may include mood changes, food cravings, neck stiffness, frequent yawning, and increased thirst.
  2. Aura: Not everyone experiences this phase, but for those who do, it usually occurs before or during the headache. Symptoms include visual disturbances (flashes of light, blind spots), tingling in the face or hands, or speech difficulties.
  3. Headache: This is the most intense phase, characterised by severe throbbing or pulsing pain, usually on one side of the head. It may be accompanied by nausea, vomiting, and extreme sensitivity to light and sound.
  4. Postdrome: After the headache subsides, you may feel drained, fatigued, or confused. Some people report a feeling of elation or relief during this recovery phase.

How Long Does a Migraine Last?

A migraine attack typically lasts between 4 and 72 hours if left untreated. However, the overall migraine experience may last longer when the prodrome and postdrome phases are included.

  • Prodrome: Hours to two days before the headache
  • Aura: Usually 5 to 60 minutes
  • Headache: Typically 4 to 72 hours
  • Postdrome: Up to 24 hours after the headache

Not everyone experiences every stage, and the duration can vary from person to person.

How Are Migraines Diagnosed?

Migraines are usually diagnosed based on your symptoms, medical history and a physical examination. Your doctor will ask about the frequency, duration and severity of your headaches, as well as any associated symptoms such as nausea, visual disturbances or sensitivity to light.

In most cases, and in line with NICE guidance on headache assessment, brain scans such as CT or MRI scans are not required unless your symptoms suggest another underlying condition or there are warning signs that need further investigation.

Keeping a headache diary can also help your doctor identify migraine patterns and recommend the most appropriate treatment.

What Kind of Food Should I Avoid for Migraines?

Diet plays a significant role in managing symptoms. Certain foods are known to trigger migraines in some people, and avoiding these can help reduce the frequency and severity of your attacks. Foods to watch out for include:

  • Aged Cheeses: Foods like cheddar, blue cheese, and Parmesan contain high levels of tyramine, a compound that can trigger migraines.
  • Processed Meats: Sausages, hot dogs, and deli meats often contain nitrates, which are known migraine triggers.
  • Alcohol: Red wine is a common trigger, but other alcoholic beverages can also cause migraines due to their tyramine content and the dehydration they cause.
  • Caffeine: While moderate caffeine consumption can sometimes relieve a migraine, too much caffeine or withdrawal from caffeine can trigger one.
  • Artificial Sweeteners: Aspartame and other artificial sweeteners can trigger migraines in some people.
  • Chocolate: Though a beloved treat, chocolate contains both caffeine and beta-phenylethylamine, which can trigger migraines in susceptible individuals.
  • MSG (Monosodium Glutamate): Often found in processed foods and restaurant meals, MSG can lead to migraines for some people.

How Are Migraines Treated?

Although there is no cure for migraines, treatment can help reduce symptoms and prevent future attacks.

Common treatment options include:

  • Resting in a quiet, dark room
  • Drinking plenty of fluids to stay hydrated
  • Taking over-the-counter pain relief early in the attack
  • Prescription migraine medications, such as triptans
  • Anti-sickness medication if nausea or vomiting occurs
  • Preventive medication for people with frequent migraines

Lifestyle changes can also help reduce migraine frequency. Maintaining a regular sleep routine, staying hydrated, managing stress and avoiding known triggers are all important parts of migraine management.

When Should You Seek Medical Advice?

Most migraines can be managed with lifestyle changes and appropriate treatment. However, you should arrange a medical assessment if:

  • Your migraines become more frequent or severe.
  • Over-the-counter medication is no longer effective.
  • Your symptoms interfere with work or daily life.
  • You develop migraines for the first time after the age of 50.

Seek urgent medical attention immediately if you experience:

  • A sudden, severe headache unlike any you've had before
  • Weakness or numbness on one side of the body
  • Difficulty speaking or understanding speech
  • Confusion or loss of consciousness
  • A headache following a head injury
  • A headache accompanied by fever, neck stiffness or seizures

These symptoms could indicate a more serious medical condition and require immediate assessment.
