Chronic Migraines

Chronic migraines are frequent headaches that happen 15 or more days each month. They can cause more than head pain, including nausea, light sensitivity, and vision changes. Getting the right diagnosis and treatment plan can help reduce how often they happen and how much they affect your daily life.

Overview

What Are Chronic Migraines?

Chronic migraines are diagnosed when someone has headaches 15 or more days a month for at least three months, and at least eight of those days have migraine symptoms. Unlike occasional migraines, chronic migraines can interfere with work, family life, and everyday routines.

Migraine pain is often throbbing and may affect one side of the head. Some people also experience nausea, vomiting, and sensitivity to light and sound. Others experience visual changes called aura, such as flashing lights or blind spots. Chronic migraines are considered a brain disorder that changes how the body processes pain.

Common Types of Chronic Migraines

Chronic migraines can look different from person to person. Understanding the type of migraine you have can help guide treatment.

Chronic Migraine Without Aura

Frequent headaches with typical migraine symptoms, but no warning signs before the pain begins. The pain is usually moderate to severe and may get worse with movement.

Chronic Migraine With Aura

Includes temporary symptoms before or during the headache, such as flashing lights, blind spots, or tingling in the face or hands.

Medication Overuse Headache

Can develop when migraine medications are taken too often. This may lead to rebounding headaches and more frequent pain.

Hemiplegic Migraine

A rare type of migraine that can cause temporary weakness on one side of the body. Because it can look like a stroke, medical evaluation is important.

Vestibular Migraine

Often it causes dizziness, balance problems, or a spinning feeling. Head pain may or may not be present.

Menstrual-Related Chronic Migraine

Linked to hormone changes during the menstrual cycle. Migraines may become more frequent or more intense around this time.

What Causes Chronic Migraines

Chronic migraines usually develop from a mix of genetic factors, brain sensitivity, and environmental triggers. Changes in brain chemicals, including serotonin and CGRP, play an important role in how migraines start and continue.

Genetics

If migraines run in your family, you may be more likely to develop them.

Hormonal Changes

Shifts in estrogen levels during menstruation, pregnancy, or menopause can trigger migraines.

Stress

Emotional or physical stress is a common trigger and may increase how often migraines occur.

Sleep Disruption

Poor sleep, irregular schedules, or sleep disorders can make migraines more frequent.

Dietary Triggers

Some people are sensitive to certain foods or drinks, including alcohol or aged cheeses.

Neurological Sensitivity

People with chronic migraines often have a nervous system that is more sensitive to pain signals.

Treatments That Remedy Chronic Migraines

Managing chronic migraines often involves more than one approach. A treatment plan may include preventive medication, medicine taken during attacks, lifestyle changes, and sometimes in-office procedures. The goal is to reduce both the number of migraines and how severe they are.

Botox for Migraines

Botox is FDA approved for chronic migraine, defined as fifteen or more headache days per month. The protocol uses a fixed pattern of injections across the forehead, temples, back of the head, neck, and shoulders every twelve weeks. Most patients notice benefit after the second cycle.

Botox for TMJ / Jaw Clenching & Teeth Grinding

Headaches that are present on waking and centered at the temples often originate from overnight clenching rather than migraine physiology. Treating the masseter and temporalis muscles addresses that source directly.

Jaw Slimming / Masseter Reduction

The same injection target used for facial slimming reduces the force of the bite. Patients who come in for jawline contouring frequently report fewer tension headaches as a secondary effect within the first month.

Sleep Optimization / Poor Sleep Treatment

Disrupted sleep is both a documented migraine trigger and a consequence of frequent attacks. Stabilizing sleep timing is one of the few interventions that reduces attack frequency without medication.

IV Nutrient Therapy / IV Drip

Magnesium and riboflavin have the strongest evidence among nutrients studied for migraine prevention, and dehydration is a common trigger. Intravenous delivery is used when oral supplementation is poorly tolerated or absorption is in question.

Hormone Replacement Therapy – Women (HRT)

Migraines that cluster around menstruation or intensify through perimenopause track with falling estrogen. Stabilizing levels can reduce frequency, though estrogen therapy requires careful assessment in patients who experience migraine with aura.

Related Concerns to Chronic Migraines

Chronic migraine usually presents alongside other patterns. Patients tracking headache frequency often find the same triggers appear in their jaw tension, sleep quality, and hormonal cycle.

Jaw Pain / TMJ

Joint dysfunction refers pain into the temple and behind the eye, which is where many patients locate their migraines. Clicking, limited opening, and jaw fatigue point toward this source.

Jaw Pain / TMJ

Jaw Clenching & Teeth Grinding

Overnight clenching produces headaches concentrated in the morning hours. Tooth wear, an enlarged jaw muscle, and a partner reporting grinding are the findings that separate this from primary migraine.

Neck & Shoulder Tension

Tension originating at the base of the skull refers upward and is often the first sensation patients notice before an attack. This is why standard migraine injection patterns extend into the neck and shoulders.

Neck & Shoulder Tension

Poor Sleep / Insomnia

Both insufficient and excessive sleep trigger attacks, which is why weekend migraines are so common. Consistency of timing matters more than total hours.

Poor Sleep / Insomnia

Brain Fog

Cognitive slowing frequently persists for a day after the pain resolves, a phase clinicians call the postdrome. Patients often log only the headache hours and underestimate how much time an attack actually costs them.

Brain Fog

Hormonal Imbalance

Attacks that track with the menstrual cycle, pregnancy, or perimenopause point toward a hormonal contributor. Charting headache days against cycle days is the fastest way to confirm the pattern.

Frequently Asked Questions

Diagnosis is based on how often headaches occur, what symptoms are present, and your medical history. Imaging tests are only used if another condition needs to be ruled out.

There is no permanent cure, but many treatments can significantly reduce how often migraines happen and how severe they are.

OnabotulinumtoxinA is FDA-approved for chronic migraine prevention and has been shown to be safe when given by a trained provider.

Some treatments begin to help within a few weeks, while others may take several months for full results.

If headaches occur more than 15 days per month or regularly disrupt your daily life, it is reasonable to seek evaluation from a qualified provider.
