The patient presented to the GP clinic on two prior occasions requesting stronger analgesics. OTC medications were deemed insufficient, and the pattern of escalating frequency prompted specialist referral. No imaging had been performed at the time of referral. SECTION 2 — REASON FOR ENCOUNTER & CHIEF COMPLAINT CHIEF COMPLAINT (Patient's Own Words): "My headaches have become so much more frequent and way more severe — they are ruining my life." 2.1 Complaint Characterization Primary Complaint: Increasing frequency and severity of headache episodes Duration of Complaint: Progressive worsening over past 3–6 months Functional Impact: Missing classes/work, reduced social activity, impaired concentration Patient's Primary Fear: "Something serious is wrong with my brain" — anxiety-driven health concern Urgency Level: Moderate-High — warrants urgent specialist evaluation Prior Interventions: OTC ibuprofen, acetaminophen — partially effective; tolerance developing 2.2 Headache Frequency Timeline TIME PERIOD FREQUENCY SEVERITY (VAS) 6 months ago 1–2 per month 3–5/10 (mild-moderate) 3–4 months ago 1–2 per week 5–7/10 (moderate) 1–2 months ago 3–4 per week 6–8/10 (moderate-severe) Current (Week 9) 4–6 per week 7–9/10 (severe) Average episode duration 6–24 hours Peak at 4–8 hours Longest single episode Up to 72 hours Bedridden — unable to work 2.3 Impact on Activities of Daily Living (ADLs) • Academic performance: Missed 6 lectures and 2 examinations due to headache in the past month • Occupational: Reduced productivity; difficulty meeting deadlines; 3 sick days taken • Social: Cancelled social engagements, avoided parties due to light/noise sensitivity • Physical: Unable to exercise on headache days; avoids outdoor activities • Sleep: Headaches both disrupt sleep and are triggered by poor sleep — vicious cycle documented • Mental health: Significant worry about headache etiology; PHQ-2 screen positive • Quality of life (MIDAS score estimate): Grade IV — Severe Disability SECTION 3 — HISTORY OF PRESENT ILLNESS — OPQRST ANALYSIS 3.1 OPQRST Table — Systematic HPI Breakdown DIMENSION CLINICAL DESCRIPTION Onset (O) Gradual and insidious onset approximately 3–6 months prior to this encounter. Patient recalls first episode as "unusual" — dismissed as exam stress. Frequency escalated progressively. No single precipitating event identified at initial onset. No history of trauma, infection, or major life event coinciding with onset. Pattern is consistent with a primary headache disorder entering a transformed phase. Provocation & Palliation (P) PROVOCATION: Physical exertion (exercise, climbing stairs), prolonged screen exposure (3–8 hours/day), bright fluorescent lighting, loud environments, skipping meals, poor hydration (1L water/day), sleep deprivation (6 hours), hormonal fluctuations (if female — peri-menstrual pattern), red wine, aged cheeses, processed meats (nitrate-containing), high-stress academic periods, weather changes (barometric pressure drops), strong perfumes, and altitude changes. PALLIATION: Rest in a dark and quiet room, cold compress to forehead/neck, sleep, ibuprofen 600 mg (moderate relief), caffeine (limited, short-term relief — worsens cycle), vomiting (paradoxically relieves pain in some attacks). Quality (Q) Primarily described as throbbing, pulsating, and pounding — classic migrainous quality. Some episodes described as pressure-like or tight (tension component). Occasional stabbing or sharp "ice-pick" sensations superimposed on the dull ache. The character of pain can vary within and between attacks. During peak intensity, any movement exacerbates pain significantly. Radiation (R) Predominantly unilateral — alternates between left and right hemispheric predominance across different attacks (important: does NOT always lateralize to same side). Radiation patterns: temporal → frontal → orbital region. Some attacks begin occipitally and radiate anteriorly. Neck and shoulder pain accompanies approximately 60% of episodes. No radiation to jaw, teeth, or ear suggesting temporomandibular or otological cause. Severity (S) VAS (Visual Analogue Scale): 7–9/10 at peak during worst episodes. Patient rates average attack as 7/10. Functional disability scale: MIDAS Grade IV (21 days lost in past 3 months). HIT-6 (Headache Impact Test) score estimated at 60+ — Severe impact. Patient describes worst attacks as preventing any activity — confined to bed in darkness for up to 72 hours. Timing (T) Current frequency: 4–6 episodes per week (transformed migraine territory). Duration per episode: 6–72 hours. Attacks often begin in the morning upon waking or within 1–2 hours of rising. No consistent diurnal pattern across all attacks. Some episodic attacks on weekends — "let-down" or stress-relief migraine. Postdromal phase (fatigue, cognitive fog, mood changes) lasting 4–24 hours post-headache common. Context / Associated (C) High-pressure academic environment (examination period). Sleep deprivation — 4–5 hours/night for past 8 weeks. High caffeine intake (4–5 cups coffee daily). Irregular meal timing — often skips breakfast. Sedentary lifestyle — no regular exercise. Screen exposure 8–10 hours/day. Mild psychosocial stressors: relationship, financial, academic pressures. No recent head trauma, infection, or neurological events. 3.2 Headache Diary Reconstruction — Past 2 Weeks Based on patient recall and review, the following headache diary was reconstructed to capture recent attack patterns. Formal diary initiation is recommended going forward.
