Have had migraines since high school, now 62. Worst trigger for me for years has been smells (perfume, cologne, dryer sheets, smoke, etc.) My sister (who lives in Indiana and I live in Michigan) showed up at my house last week. Has a reunion later that evening so stopped by for a visit (Haven't seen or heard from her in years). Told her when she called I can't have anyone scented in my house and she said "all she put on was deodorant". The smell of dryer sheets coming off her clothes was so strong even sitting outside the entire 4 hours she was over. It even gave my husband a headache. So tired of telling people the same thing over and over and them not even realizing all of the things they use on themselves and their homes that will trigger severe headache, nausea, vomiting, etc.
