Chronic Migraine
Overview
Chronic migraine is defined as 15 or more headache days per month for at least three months, with at least eight of those days meeting criteria for migraine. It is a neurological condition — not simply "a bad headache" — involving altered brain chemistry, cortical spreading depression, and sensitization of the trigeminal pain pathway. Chronic migraine is a leading cause of disability worldwide and is frequently undertreated.
Common Symptoms
•Moderate to severe throbbing or pulsating head pain, typically one-sided
•Nausea and/or vomiting during attacks
•Significant sensitivity to light (photophobia) and sound (phonophobia)
•Aura preceding or accompanying attacks in some patients (visual, sensory, or speech disturbances)
•Postdrome ("migraine hangover") — fatigue, cognitive fog, and mood changes after the headache resolves
•Escalating frequency of headaches that increasingly disrupts work and personal life
Common Causes
•Genetic predisposition (migraine is highly heritable)
•Hormonal fluctuations (particularly estrogen changes in women)
•Medication overuse (analgesic rebound headache is a major contributor to chronification)
•Psychological stress, disrupted sleep, and irregular meals as consistent triggers
•Obesity, sleep apnea, and anxiety/depression — all known comorbidities that worsen migraine burden
•Sensory triggers: bright lights, strong odors, weather changes
Who May Benefit from Treatment
Adults experiencing frequent disabling headaches — particularly those who have tried multiple acute medications without sufficient relief, or whose headache frequency has increased over time — are strong candidates for a pain management evaluation. Patients with chronic migraine who have not responded to standard preventive therapies (topiramate, amitriptyline, beta-blockers) are especially appropriate for the advanced options available at Echo PMR.
Treatment Options at Echo PMR
•Greater occipital nerve blocks — a frontline interventional option for rapid migraine cycle interruption
•Sphenopalatine ganglion (SPG) blocks targeting a key autonomic ganglion involved in migraine pathophysiology
•Trigger point injections in the cervical and pericranial musculature to address myofascial contributors
•Medication management including CGRP monoclonal antibody therapy coordination, preventive agents, and acute rescue medications
•Botulinum toxin (BOTOX®) injection protocol for chronic migraine prevention per established clinical guidelines
•Ketamine infusion therapy for refractory chronic migraine with significant central sensitization
Recovery Expectations
Most patients with chronic migraine see a reduction in headache days per month within 60 to 90 days of initiating a comprehensive preventive strategy. Interventional procedures such as occipital nerve blocks often provide faster relief — sometimes within 48 to 72 hours — and serve as a bridge while longer-term preventive medications take effect. The realistic goal is to reduce migraine frequency, shorten episode duration, and improve responsiveness to acute medications.
When to Seek Care
If you are having headaches 15 or more days per month, if your headaches are worsening in frequency or severity, or if migraine is significantly affecting your ability to work or care for your family, call Echo PMR. You do not have to manage this condition alone — effective, evidence-based treatment can dramatically improve your quality of life.
