migraine on one side

Overview

A migraine is a type of headache that can cause intense, throbbing pain, usually on one side of the head. It often comes with other symptoms like nausea, vomiting, and sensitivity to light or sound. Migraines are a neurological condition, meaning they involve the brain and nerves.

Yes, migraine is very common. About 1 in 7 people worldwide experience migraines. It is one of the most common neurological conditions.

Migraines can affect anyone, but they are more common in women than in men. They often start in teenage years or early adulthood, but children and older adults can get them too.

Symptoms

Common symptoms

• Throbbing or pulsing pain on one side of the head
• Nausea or vomiting
• Sensitivity to light, sound, or smells
• Blurred vision or seeing spots
• Feeling very tired or weak

Symptoms in children

• Pain on one or both sides of the head
• Pale skin and feeling sick to the stomach
• Needing to lie down in a dark, quiet room
• Dizziness or trouble concentrating

Symptoms in older adults

• Headache may be less severe but last longer
• More likely to have aura (visual changes) without head pain
• Increased sensitivity to light and sound
• May be mistaken for other conditions like stroke

Causes

Main causes

• The exact cause is not fully known. Migraines are thought to be due to changes in brain activity and how nerves send pain signals.
• Genetic factors – migraines often run in families.
• Triggers can include stress, changes in sleep, certain foods or drinks (like aged cheese, chocolate, alcohol), weather changes, and hormonal changes (like during periods).

Risk factors

• Having a family history of migraines
• Being female (due to hormone fluctuations)
• Age – most common between 10 and 40 years old
• Medical conditions like depression, anxiety, or sleep disorders

When to see a doctor

See a doctor urgently if:

• If you have a headache with stiff neck, fever, or rash
• If you have a headache after a head injury
• If you have sudden weakness or trouble speaking

Book a routine appointment if:

• If you have frequent headaches (more than once a week) that affect your daily life
• If over‑the‑counter pain relief does not help
• If your headaches are becoming more severe or changing pattern

Diagnosis

A doctor can usually diagnose migraines by asking about your symptoms, medical history, and doing a physical exam. There is no single test for migraine.

Tests that may be done

• Your doctor may ask you to keep a headache diary to track symptoms and triggers.
• Sometimes blood tests, a CT scan, or an MRI scan are done to rule out other causes.

What to expect at your appointment

Your doctor will ask you to describe your headaches in detail: how often they happen, what the pain feels like, where it hurts, and any other symptoms. This helps them make an accurate diagnosis.

Treatment

Treatment for migraine aims to stop symptoms when they happen and prevent future attacks. It includes self‑care and medical treatments. Your doctor will work with you to find the best approach.

Self-care at home

• Rest in a dark, quiet room
• Apply a cold or warm compress to your head or neck
• Drink plenty of water
• Try relaxation techniques like deep breathing or meditation
• Avoid known triggers like certain foods or bright lights

Medical treatments

Your doctor may recommend medications to stop an attack (acute treatment) or to prevent attacks (preventive treatment). These include pills, nasal sprays, or injections. No specific drug names or doses are given here – ask your doctor what is right for you.

When is surgery considered?

Surgery is very rarely used for migraines. Some procedures, like nerve blocks or trigger point injections, may be considered if other treatments fail. Discuss with a neurologist.

Living with this condition

Living with migraines means learning to manage triggers and knowing what to do when an attack starts. Keeping a headache diary can help you spot patterns.

Lifestyle tips

• Try to keep a regular sleep schedule
• Manage stress with exercise, yoga, or talking to someone
• Stay hydrated and eat regular meals
• Avoid your known triggers

Diet and exercise

Eating balanced meals and staying hydrated may help reduce migraine frequency. Regular gentle exercise, like walking or swimming, can also help, but avoid very intense exercise that might trigger an attack.

Mental health and emotional wellbeing

Living with migraines can be frustrating and may lead to anxiety or depression. It is important to talk to your doctor about how you are feeling. If you are struggling, reach out to a mental health professional or a crisis support line.

Prevention

Migraines cannot always be prevented, but you can reduce how often they happen and how bad they are by avoiding triggers and taking preventive medicines if prescribed by your doctor.

Complications

If left untreated

• Chronic migraine – having 15 or more headache days per month
• Medication overuse headache – from using too much pain relief
• Missing school, work, or social activities
• Increased risk of anxiety and depression

Long-term outlook

With the right treatment and lifestyle changes, most people with migraines can manage their symptoms and lead a full life. It often takes time to find what works best for you, but help is available.
