Is it possible to not know you have a migraine?

It is possible to not know that you have a migraine, especially if it is your first migraine or if you have not experienced migraines before. Some people may mistake their migraine symptoms for other conditions, such as sinus infections or tension headaches. Additionally, some people may have migraines without the severe headache pain that is typically associated with migraines. These types of migraines are known as "silent migraines" or "acephalgic migraines".
