Chronic Migraine & Headache Disorders

Comprehensive headache evaluation, migraine management, neuropathic pain treatment, and preventive therapy planning by Dr. Chetan Padghan in Pune.

Understanding Headache Disorders

Headache disorders are among the most common neurological conditions worldwide. While most headaches are primary (not caused by an underlying disease), some headaches can signal serious neurological conditions. Accurate diagnosis is the key to effective treatment.

Dr. Chetan Padghan provides comprehensive headache evaluation, distinguishing between primary headache disorders and secondary causes, and developing individualized treatment plans.

Types of Headache Disorders

Migraine

A neurological condition characterized by recurrent episodes of moderate to severe headache:

Migraine Without Aura:

Throbbing or pulsating headache, usually one-sided
Duration of 4–72 hours
Associated with nausea, vomiting, light sensitivity (photophobia), and sound sensitivity (phonophobia)
Worsened by physical activity
May be triggered by stress, hormonal changes, certain foods, sleep disturbances, or weather changes

Migraine With Aura:

Preceded by neurological symptoms (aura) lasting 5–60 minutes
Visual aura — flashing lights, zigzag lines, blind spots
Sensory aura — tingling or numbness, usually starting in the hand and spreading to the face
Language aura — difficulty speaking or word-finding problems

Chronic Migraine:

Headache occurring 15 or more days per month for at least 3 months
At least 8 days with migraine features
Often associated with medication overuse
Significantly impacts quality of life and productivity

Tension-Type Headache

The most common primary headache
Bilateral, pressing or tightening quality (“band-like”)
Mild to moderate intensity
Not worsened by physical activity
No nausea or vomiting (mild sensitivity to light or sound may occur)
Episodic or chronic forms

Cluster Headache

Severe, strictly one-sided headache around the eye or temple
Duration of 15–180 minutes, occurring multiple times daily
Accompanied by autonomic features — tearing, nasal congestion, eyelid swelling, facial sweating
Occurs in clusters lasting weeks to months, followed by remission periods
One of the most painful headache conditions known

Other Headache Types

Medication overuse headache — chronic headache worsened by frequent use of painkillers
Trigeminal neuralgia — brief, severe, electric shock-like facial pain
Occipital neuralgia — sharp pain at the back of the head
New daily persistent headache (NDPH) — sudden onset of daily headache that persists
Hemicrania continua — continuous one-sided headache responsive to indomethacin
Thunderclap headache — sudden, severe headache reaching maximum intensity within seconds (requires emergency evaluation)

Warning Signs — When Headache Is Dangerous

Certain headache features require urgent evaluation to rule out serious conditions:

Thunderclap headache — sudden, severe headache (“worst headache of my life”)
Progressive worsening — headaches that are getting worse over weeks
Neurological symptoms — weakness, vision changes, confusion, speech problems
Fever with headache — may indicate meningitis or encephalitis
New headache after age 50 — increased concern for secondary causes
Headache with papilledema — swelling of the optic nerve (raised intracranial pressure)
Change in pattern — a new or different type of headache in someone with known headaches
Post-traumatic headache — following head injury

Diagnostic Approach

Clinical Evaluation

Detailed headache history — frequency, duration, location, quality, severity, associated symptoms
Headache diary review — patterns, triggers, medication use
Impact assessment — effect on work, social life, and daily activities
Neurological examination
Fundoscopy — to check for papilledema

Investigations (When Indicated)

Brain MRI with contrast — to rule out structural causes (tumors, vascular malformations, sinus disease)
MR angiography/venography — for vascular causes, cerebral venous thrombosis
CT brain — for urgent evaluation of thunderclap headache (subarachnoid hemorrhage)
Lumbar puncture — for suspected raised intracranial pressure, meningitis
Blood tests — inflammatory markers (ESR, CRP) for temporal arteritis in older patients

Treatment Approach

Acute Treatment

Migraine — triptans (sumatriptan, rizatriptan), NSAIDs, anti-emetics, combination analgesics
Cluster headache — high-flow oxygen therapy, subcutaneous sumatriptan
Tension-type headache — simple analgesics, NSAIDs
Avoiding overuse of acute medications (limit to 2–3 days per week maximum)

Preventive Treatment

Preventive therapy is recommended when headaches are frequent (4+ migraine days per month), disabling, or when acute medications are overused:

Beta-blockers — propranolol, metoprolol
Antidepressants — amitriptyline, venlafaxine
Anti-seizure medications — topiramate, valproate
Calcium channel blockers — flunarizine
CGRP monoclonal antibodies — erenumab, fremanezumab, galcanezumab (newer targeted therapies)
Botulinum toxin (Botox) — for chronic migraine
Verapamil — for cluster headache prevention

Medication Overuse Headache Management

Education about the role of medication overuse in perpetuating headaches
Structured withdrawal of overused medications
Bridging therapy during withdrawal
Initiation of appropriate preventive therapy
Close follow-up and support during transition

Non-Pharmacological Approaches

Lifestyle modifications — regular sleep, exercise, hydration, stress management
Trigger identification and avoidance
Cognitive behavioral therapy (CBT) for headache
Relaxation techniques — biofeedback, progressive muscle relaxation
Yoga and meditation
Regular aerobic exercise

Living with Chronic Headache

Maintaining a headache diary to track patterns and triggers
Adhering to preventive medication schedules
Regular follow-up for treatment optimization
Balancing activity and rest
Addressing comorbid conditions — anxiety, depression, sleep disorders
Patient support and education
