Why are migraines so painful? How is a headache sensed?
From my understanding, (a) the brain has no nerves, which is why you can talk to people while doing brain surgery on them; and (b) headache is caused by blood vessels constricting. Now, I am unsure whether migraines are also caused by blood vessels constricting, but in any case - what is it that is doing the sensing of this pain? Or is it a(nother) case of the brain just making shit up because it hates me?
Not really a biology question, except in the broadest of senses. Fortunately there's other specialists for that:

Yeah I know it's merely "biology adjacent", but I couldn't find a better community to ask.
Thank you for the video link, much of my question seems to be answered by the section on referred pain.
