There's an ant called the bullet ant, so named because its sting feels like getting shot. Its Wikipedia page shows other similar nicknames in Spanish and in Portuguese. So, given that other bugs' stings have already been described as comparable to getting shot, I believe it when you say that they say the millipede's bite feels equally painful.
