I really enjoyed this vote. One symptom I have very often that I didn't see listed is a heightened sense of smell before and during all the stages of my migraine attack. And those smells connect with my nausea symptoms and pain symptoms, i.e.pulsing, pounding, stabbing.
Would it be possible to show which percentage of people suffer from the different warning signs instead of what is shown now? (which is the percentage of answers which isn't that interesting).
Your quiz, and therefore the results, are faulty. It would only allow me to check ten items. The items lower on the list may not be accurately represented or reported.
