Reassess the Diagnosis: This is Likely Migraine, Not Sinusitis
Stop treating for sinusitis and initiate triptan therapy for migraine—this patient's presentation is classic for migraine without aura, not bacterial sinusitis. The absence of nasal congestion, normal smell, lack of fever, and failure to respond to antibiotics after one week effectively rules out acute bacterial sinusitis 1, 2.
Why This is Migraine
This patient meets diagnostic criteria for migraine without aura 1:
- Frontal pressure headache (bilateral location occurs in ~40% of migraine patients)
- Non-pulsatile quality (while pulsating is typical, it's not required)
- Mild nausea (classic associated symptom)
- Duration >1 week (consistent with prolonged attack or multiple attacks)
- No sinus symptoms (no nasal congestion, normal smell, no fever)
The "sinus pressure" description is a common migraine misattribution—many patients incorrectly attribute frontal migraine pain to their sinuses 1.
Immediate Next Steps
1. Discontinue Clavulin Immediately
The antibiotic has failed after one week and is unnecessary. There are no clinical features of bacterial sinusitis 3.
2. Initiate Migraine-Specific Therapy
For acute treatment:
- Add a triptan to the NSAID regimen (strong recommendation) 4, 2
- Options include: sumatriptan, rizatriptan, naratriptan, or zolmitriptan
- Critical contraindication check: Triptans should NOT be used with uncontrolled hypertension 2
3. Address the Blood Pressure First
This is the critical barrier to optimal treatment. Her BP has worsened from 140/90 to 150/90, representing stage 2 hypertension. You cannot safely prescribe triptans until her hypertension is controlled 2.
Immediate BP management:
- Initiate or optimize antihypertensive therapy
- Consider agents that also prevent migraine (dual benefit):
4. Bridge Therapy While Controlling BP
Until hypertension is controlled and triptans can be safely used:
- Continue NSAIDs (ibuprofen 400-800mg or naproxen 550mg) as first-line 2, 7
- Add caffeine if not already included (aspirin-acetaminophen-caffeine combination is effective) 2, 8
- Limit NSAID use to <15 days/month to prevent medication-overuse headache 2, 6
Common Pitfalls to Avoid
Medication-overuse headache risk: She's already been using NSAIDs for one week. Counsel her to limit acute medication use to no more than twice weekly once symptoms improve 2. If she requires acute treatment more than 2 days/week, she needs preventive therapy 2.
Triptan contraindication: Do not prescribe triptans with BP ≥140/90. The guidelines explicitly state triptans should not be used in patients with uncontrolled hypertension or those at risk for heart disease 2.
Missing secondary causes: While this presentation is consistent with primary migraine, her elevated BP warrants consideration of secondary headache. However, she has no red flags (no fever, neck stiffness, focal deficits, visual changes, or trauma) that would mandate neuroimaging at this time 8.
Follow-Up Plan
Within 1-2 weeks:
- Recheck BP to confirm control (<140/90)
- Once BP controlled, prescribe triptan + NSAID combination
- Assess headache frequency with a headache diary 2
If headaches occur ≥2 times per week: Initiate preventive therapy with an agent that also treats hypertension (ARB, lisinopril, or beta-blocker) 9, 5.
If headaches persist despite treatment: Consider alternative diagnoses including chronic migraine, medication-overuse headache, or rarely, idiopathic intracranial hypertension (though she lacks papilledema symptoms) 10, 11, 12.
Hypertension Considerations
The elevated BP itself is unlikely to be causing her headache—hypertension-related headache requires BP ≥180/120 mmHg with demonstrated temporal relationship 13. However, her hypertension must be controlled before optimal migraine therapy can be safely initiated and represents an important cardiovascular risk factor requiring management regardless of headache etiology 14.
