片方の目の周りがひどく痛む発作があります。群発頭痛とはどんな病気で、普通の頭痛と何が違う？ Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: 月曜；頭痛外来の相談. Kitchen/home right now: 暗室、日記. Already tried: 市販薬だけ増やす. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.
