What Are the Symptoms of a Migraine

If you have ever experienced a severe, throbbing headache accompanied by nausea, light sensitivity, or visual disturbances, you may already be familiar with the debilitating impact of a migraine. Yet despite being one of the most common neurological conditions in the world affecting approximately one in seven people in the UK migraine symptoms are frequently misunderstood, dismissed as a bad headache, or left untreated for years.
In this guide, Mr Amit our consultant neurosurgeon at Renew Skin & Health Clinic in Leamington Spa explains what migraines are, the different types of migraines, their common migraine causes and triggers, and when specialist intervention such as migraine injection treatment may be appropriate.

A migraine is a complex neurological condition that causes recurrent, often severe headaches, typically accompanied by a range of other symptoms. Unlike a tension headache, a migraine headache is not simply a matter of head pain it is a full neurological event that can last anywhere from a few hours to several days and can significantly disrupt everyday life, work, and emotional wellbeing.

The exact mechanisms underlying migraines are not yet fully understood; however, current evidence suggests that they involve abnormal brain activity that affects nerve pathways, blood vessels, and chemical messengers such as serotonin. This neurological activity triggers the characteristic pain and associated migraine headache symptoms that patients experience.

Migraine symptoms vary between individuals and can differ from one episode to the next. However, many patients experience a recognisable pattern of symptoms that unfolds across four distinct phases.

Phase 1: Prodrome (Before the Headache)

• Hours or even days before a migraine headache begins, many patients notice subtle warning signs, including:
• Mood changes irritability, low mood, or unusual feelings of heightened energy
• Food cravings, particularly for sweet or salty foods
• Increased thirst and frequent urination
• Neck stiffness or muscle tension
• Yawning more frequently than usual
• Fatigue or difficulty concentrating

Phase 2: Aura

Approximately one in three people who experience migraines will also experience migraine aura  a series of reversible neurological symptoms that typically develop gradually over five to sixty minutes and precede the headache phase. Aura symptoms can include:

• Visual disturbances — flashing lights, zigzag lines, blind spots, or tunnel vision (the most common form of aura)
• Pins and needles or numbness spreading across one side of the face or body
• Temporary weakness on one side of the body
• Difficulty speaking or finding words

It is important to note that some patients experience migraine aura without headache  sometimes called a silent migraine where aura symptoms occur without any subsequent head pain. This can be alarming and is sometimes mistaken for a transient ischaemic attack (TIA). If you experience sudden, unexplained visual or neurological symptoms for the first time, always seek urgent medical advice.

Phase 3: The Headache Phase
The headache phase of a migraine can last between four and seventy two hours if left untreated. Migraine symptoms during this phase commonly include:

• Moderate to severe throbbing or pulsing pain, usually on one side of the head
• Pain that worsens with physical activity, movement, or bending forward
• Nausea and vomiting
• Heightened sensitivity to light (photophobia)
• Heightened sensitivity to sound (phonophobia)
• Sensitivity to smells (osmophobia) in some patients
• Pallor and sweating

Phase 4: Postdrome (After the Headache)
Once the headache subsides, many patients enter a postdrome phase lasting up to 48 hours, during which they may feel drained, confused, or unusually tired. Some patients describe this phase as a ‘migraine hangover’. Difficulty concentrating and mild head discomfort may persist during this period.

There are several recognised types of migraines, each with distinct features. Understanding which type you experience is important because it directly influences which treatment approach is most appropriate.

The precise migraine causes are not fully established, but research indicates that migraines arise from a combination of genetic predisposition and environmental factors. Individuals with a family history of migraines are significantly more likely to experience them themselves.

From a neurological standpoint, migraines are associated with abnormal electrical activity in the brain (known as cortical spreading depression), which triggers a cascade of inflammatory and vascular changes that produce the characteristic pain and symptoms.

While migraine triggers do not cause migraines directly, they can initiate an attack in people who are already predisposed. Identifying and managing your personal triggers is one of the most effective strategies for reducing the frequency of migraines. Common triggers include:

• Stress and anxiety — the most widely reported trigger; migraines often occur after a period of intense stress or during a ‘let down’ period
• Hormonal changes — oestrogen fluctuations during the menstrual cycle, pregnancy, or the menopause are a significant trigger for many women
• Sleep disturbances — both insufficient sleep and excessive sleep can trigger an attack
• Dehydration — even mild dehydration can lower the threshold for a migraine
• Dietary factors — aged cheeses, processed meats, alcohol (particularly red wine), caffeine withdrawal, and skipping meals
• Sensory stimuli — bright or flickering lights, loud noise, and strong smells
• Weather changes — shifts in barometric pressure are reported as a trigger by many patients
• Certain medications — including oral contraceptives and vasodilators in susceptible individuals

For many patients, migraine relief is achieved through a combination of lifestyle adjustments, over the counter or prescription medication, and trigger management. However, for patients with frequent or chronic migraines that do not respond adequately to standard treatment, specialist intervention may be required.

Self Management and Lifestyle Measures

The following self management strategies can help reduce migraine frequency and severity:

• Maintaining a consistent sleep schedule  going to bed and waking at the same time daily
• Staying well hydrated throughout the day
• Eating regular meals to maintain stable blood sugar levels
• Managing stress through relaxation techniques, mindfulness, or talking therapies
• Limiting caffeine intake and avoiding sudden caffeine withdrawal
• Using a migraine diary to identify and avoid personal triggers

You should consider seeking specialist advice if:

• Your migraines occur more than four times per month
• Over the counter or prescription medication is no longer providing adequate relief
• You are experiencing 15 or more headache days per month (chronic migraine)
• Migraines are significantly affecting your work, family life, or mental health
• You are taking acute migraine medication on more than ten days per month

At Renew Skin & Health Clinic, Mr Amit offers a range of advanced migraine therapies, including Botox for migraines, preventive injections, and targeted nerve block injections, for patients who have not responded to conventional treatments.

For patients with chronic migraines, botox for migraines (botulinum toxin type A) is one of the most extensively researched and clinically validated preventive treatments available. It is approved by the National Institute for Health and Care Excellence (NICE) for adults who experience 15 or more headache days per month, of which at least eight meet the diagnostic criteria for migraine.

Botox works by blocking the release of chemicals involved in pain transmission at specific injection sites around the head, neck, and shoulders. Over a series of treatments, administered every 12 weeks, it can significantly reduce the number of monthly migraine days.

At Renew Skin & Health Clinic, all botox for migraines procedures are carried out by Mr Amit, who has specialist expertise in headache and pain intervention. Patients travel to our clinic from Coventry, Birmingham, Warwick, and across Warwickshire for this treatment.

Beyond Botox, Mr Amit also offers preventive migraine injections and targeted nerve block injections for patients whose migraine treatment needs require a more personalised approach. These migraine therapies are tailored to each patient’s specific migraine type, frequency, and history, and are available with prompt appointments  most patients are seen within days of their initial enquiry.

Unlike the NHS pathway where eligibility for Botox treatment is strictly regulated and waiting times can be lengthy  our private clinic provides rapid access to migraine injection treatment in Leamington Spa for patients who meet the clinical criteria.

While most migraines are not dangerous, there are certain warning signs that warrant urgent medical assessment. Seek emergency medical attention if you experience:

• A sudden, severe headache that feels like the worst of your life (thunderclap headache)
• A headache accompanied by fever, stiff neck, or a rash
• A headache following a head injury
• Neurological symptoms  such as sudden weakness, confusion, or vision loss  that are new or different to your usual migraine pattern
• A first ever severe headache occurring after the age of 50

These may indicate a more serious underlying condition and should be investigated promptly.
If your migraines are frequent, severe, or no longer responding to standard medication, contact us to discuss whether specialist migraine injection treatment may be right for you.
