More Than a Headache: The 72-Hour Sequence

A migraine is not a singular event but a multi-day neurological sequence with four distinct phases. Recognizing them allows for early intervention before the inflammatory cascade peaks.

Phase 1: Prodrome (The Warning)

Up to 48 hours before pain, your brain sends signals — intense food cravings, frequent yawning, neck stiffness. These are driven by hypothalamic activity as the brain attempts to regulate a developing chemical imbalance.

Phase 2: Aura

Experienced by 25–30% of patients. Visual zig-zags (scotomas), sensory numbness, or speech difficulties lasting 20–60 minutes. This is Cortical Spreading Depression moving across the cortex.

Phase 3: Attack

Unilateral throbbing pain, nausea, light and sound sensitivity. Can last 4–72 hours without treatment.

Phase 4: Postdrome (The Hangover)

Once pain fades, the brain requires up to 48 hours to recover. Extreme fatigue, cognitive fog, and emotional sensitivity as the brain restores its chemical balance.

Identifying your prodrome pattern is the single most effective way to intervene early. Track these warning signs consistently to build your personal prediction model.
