As a 23‑year‑old woman with a history of chronic migraine, epileptic and psychogenic seizures, functional neurological disorder, anxiety, prior concussions, and a previously identified left‑brain abnormality, who now has new left‑sided pounding headaches worsened by head movement, brief severe attacks, frequent vertigo, transient visual bulging, tinnitus, ear pressure, and a heterogeneous expansile lesion in the right maxillary sinus on CT, what urgent evaluations and management steps should I pursue?

You Need Urgent Neuroimaging and Specialist Evaluation—This Is Not Just Migraine

Given your constellation of new, progressive neurological symptoms—particularly the severe left-sided headaches worsened by movement, visual pressure sensations, vertigo, tinnitus, and the CT finding of a heterogeneous expansile maxillary sinus lesion—you require urgent brain MRI with and without contrast and immediate neurology consultation before your insurance begins. Your symptom pattern raises concern for increased intracranial pressure, structural lesions, or complications from your sinus pathology that demand evaluation now, not later.

Why This Cannot Wait

Your symptoms represent multiple red flags that distinguish this from typical migraine recurrence 1:

• Headache aggravated by head movement and positional changes (raising intracranial pressure concerns)
• Progressive headache over two weeks (suggesting evolving pathology)
• Constant visual sensation of eyes "bulging outward" (potential papilledema or increased intracranial pressure)
• New-onset vertigo with postural symptoms
• Unilateral tinnitus (left ear, same side as headache)
• Pressure symptoms involving eyes and vision with position changes
• Known brain abnormality on left side from 10 years ago (requires comparison imaging)
• Heterogeneous, expansile, possibly erosive sinus lesion with differential including sinonasal carcinoma

These features are not consistent with uncomplicated migraine and warrant immediate structural evaluation 1.

Immediate Actions Required

1. Emergency Department Evaluation or Urgent Neurology Referral

You should present to an emergency department or obtain urgent neurology consultation (within 24-48 hours) for:

• Brain MRI with and without gadolinium contrast: Essential to evaluate your known left-brain abnormality, assess for mass lesions, increased intracranial pressure, venous sinus thrombosis, or extension of your sinus pathology intracranially
• Fundoscopic examination: To evaluate for papilledema (optic disc swelling from increased intracranial pressure), which your "eye bulging" sensation could represent
• Formal visual field testing: Given your visual symptoms and history of left-eye disturbances
• Neurological examination: To document any focal deficits and assess for signs of increased intracranial pressure

Do not wait for insurance coverage to begin—many emergency departments have financial assistance programs, and delaying evaluation of potential increased intracranial pressure or mass lesions risks permanent neurological damage or mortality.

2. ENT/Otolaryngology Consultation

Your maxillary sinus lesion requires:

• Biopsy or surgical evaluation: The differential diagnosis including sinonasal carcinoma demands tissue diagnosis
• Assessment for intracranial extension: Erosive lesions can extend through the skull base
• Correlation with neurological symptoms: Your headaches, facial pressure, and tinnitus may relate to this lesion

3. Ophthalmology Evaluation

Given your visual pressure sensations, history of left-eye blurriness/ghosting, and recurrent styes:

• Comprehensive eye examination with dilated fundoscopy
• Intraocular pressure measurement: To rule out glaucoma
• Visual field testing: To assess for any field defects

What These Symptoms Suggest (Differential Diagnosis)

Your symptom complex could represent:

1. Increased intracranial pressure from:

   • Mass lesion (tumor, abscess)
   • Venous sinus thrombosis
   • Idiopathic intracranial hypertension (though less likely given focal symptoms)

2. Intracranial extension of sinus pathology:

   • Erosion through skull base
   • Intracranial abscess from sinusitis
   • Malignancy with intracranial involvement

3. Structural lesion related to previous brain abnormality:

   • Growth or change in previously identified left-brain lesion
   • New lesion development

4. Vascular pathology:

   • Cerebral venous thrombosis
   • Arteriovenous malformation

5. Complicated migraine (less likely given red flags, but possible)

Regarding Your Functional Neurological Disorder History

While you have a documented history of PNES and functional neurological disorder, this does not mean your current symptoms are functional 2. Key points:

• Patients with FND can develop organic neurological disease 2
• Your symptoms have clear red flags requiring structural evaluation 1
• Migraine and FND commonly coexist, with migraine potentially triggering functional symptoms 3, 4, 5—but this relationship does not exclude new structural pathology
• Recent research shows migraine prevalence is significantly higher in FND patients (31.5% with comorbid migraine) 5, and migraine may predate FND by up to 10 years 3

The appropriate approach is to rule out dangerous structural causes first, then consider functional overlay if imaging and examination are normal 2, 6.

If Imaging Is Normal: Migraine Management

Should urgent evaluation exclude dangerous pathology, your symptoms could represent chronic migraine transformation (you're experiencing headaches 4 days/week, approaching chronic migraine threshold of ≥15 days/month) 1.

Acute Treatment Algorithm

For current headaches 1, 7, 1:

1. First-line: NSAIDs (ibuprofen 400-800mg, naproxen 500-550mg, or diclofenac potassium 50-100mg) taken early when headache is mild

   • Avoid using more than 15 days/month (risk of medication overuse headache)

2. Second-line: Triptans (if NSAIDs inadequate after 2-3 attacks)

   • Sumatriptan 50-100mg orally, or 6mg subcutaneous if severe/rapid onset
   • Rizatriptan 10mg (fastest oral peak concentration at 60-90 minutes)
   • Take early in headache phase, not during aura
   • Avoid using more than 10 days/month (medication overuse headache risk)
   • Can combine triptan + NSAID to reduce recurrence 1, 7

3. For nausea/vomiting: Metoclopramide or domperidone 1

4. Third-line (if triptans fail or contraindicated): CGRP antagonists (gepants: ubrogepant, rimegepant) or lasmiditan 1, 7

Avoid: Opioids and butalbital-containing compounds—these are ineffective for migraine, risk dependency, and cause medication overuse headache 1, 7, 8

Preventive Therapy Indication

You need preventive therapy given 1:

• Headaches 4 days/week (16 days/month)
• Approaching chronic migraine threshold
• History of chronic migraine
• Significant disability potential
• Comorbid anxiety (influences medication choice)

Preventive medication options 1, 9:

1. Topiramate 25-100mg daily: First-line, especially if weight loss desired; you tolerated this previously

   • Start 25mg nightly, increase by 25mg weekly
   • Assess efficacy after 2-3 months

2. Amitriptyline 25-75mg nightly: Preferred if comorbid anxiety, depression, or insomnia present 1

3. Propranolol or metoprolol: Beta-blockers (if no contraindications)

4. Candesartan or lisinopril: Angiotensin system blockers 9

5. CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab): If 2-3 other preventives fail 1

   • Monthly or quarterly injections
   • Assess after 3-6 months

6. Magnesium 400-600mg daily: Over-the-counter option 9

Given your anxiety comorbidity, amitriptyline would be particularly appropriate 1. Given your previous topiramate use, restarting this is reasonable if you tolerated it well.

Medication Overuse Headache Risk

Critical warning: Using acute medications (NSAIDs ≥15 days/month, triptans ≥10 days/month) causes medication overuse headache, worsening your condition 1. This is why preventive therapy is essential for you.

Regarding Your Seizure History

Do not restart antiseizure medications without clear indication 2:

• Your seizures improved and you successfully discontinued medications
• Topiramate and valproate can serve dual purposes (seizure + migraine prevention) if seizures recur
• Antiseizure medications should not be used for PNES alone 2—psychological interventions are the evidence-based treatment for functional seizures
• If functional seizures recur, treating your migraine may improve functional symptoms 3, 4—migraine prophylaxis reduced functional seizure frequency by >50% in 73% of patients in one case series 4

Lifestyle Modifications

While awaiting evaluation and alongside any treatment 7:

• Hydration: Maintain consistent fluid intake
• Regular meals: Avoid skipping meals
• Sleep hygiene: Consistent sleep schedule (7-9 hours)
• Aerobic exercise: 30-40 minutes, 3-4 times weekly (when safe after evaluation) 9
• Stress management: Mindfulness, relaxation techniques (particularly important given your FND history)
• Avoid known triggers: Document any consistent triggers in headache diary

Critical Pitfalls to Avoid

1. Do not assume symptoms are functional/psychogenic without excluding structural pathology—your red flags demand imaging 1, 2, 6

2. Do not delay evaluation until insurance begins—potential increased intracranial pressure or malignancy requires immediate assessment

3. Do not overuse acute medications—this will worsen your headaches and create medication overuse headache 1

4. Do not restart seizure medications without clear indication—your seizures resolved, and PNES does not respond to antiseizure medications 2

5. Do not ignore the sinus lesion—this requires definitive diagnosis and may be contributing to your symptoms

Summary Action Plan

Within 24-48 hours:

• Emergency department or urgent neurology evaluation
• Brain MRI with/without contrast
• Fundoscopic examination
• Neurological examination

Within 1-2 weeks:

• ENT consultation for sinus lesion biopsy/management
• Ophthalmology evaluation
• Establish adult neurology care

If imaging normal:

• Start preventive migraine therapy (topiramate or amitriptyline)
• Use NSAIDs or triptans for acute attacks (limit frequency)
• Implement lifestyle modifications
• Consider psychology referral for anxiety and FND management

Your symptoms are too concerning to attribute to migraine recurrence or functional disorder without excluding dangerous structural causes first. The combination of progressive headache with movement sensitivity, visual pressure sensations, vertigo, and a known sinus lesion with malignant potential demands urgent evaluation regardless of insurance status.
