If it feels like a headache... isn't it a headache?
By which I mean, shouldn't that be "some headaches can easily not be realised to be caused by...", or is there gatekeeping needed in what is or isn't a 'headache'?

That said, I'm not sure how either could be mistaken for neck muscle pain.
For me the difference is usually easy. If it's a headache-headache, it's annoying and you can function (even if it hurts). If it's a migraine then I simply can't work or do any fun thing anymore, not even watching something or reading.
I can have a migraine without headache. I'm still non-functional because of all the fun aura symptoms, but I'm not in pain.
