The companion brings together onset, duration, location, pain qualities, nausea, light or sound sensitivity, visual or neurologic symptoms, possible triggers, medication response, menstrual or sleep relationships, recovery time, and functional impact. Guided check-ins help the reader record what happened, when it happened, what was being done at the time, how long the change lasted, and how it affected daily function. This creates a more useful picture than isolated memories or a single symptom rating. It also gives the reader a dependable place to retain instructions, write down questions before appointments, and note the next steps established by the care team.
