My tingling feels like I can actually feel the blister filling up with pus. (Sorry, I know that's gross, but that's what it feels like.) It is a tickling, tingling itch, if that makes sense. And yes, it lasts for several seconds to a minute at a stretch and then very soon after, starts again. It lasts intermittently like that for several days. There's also a feeling of pressure and achiness, as the blister area swells. This is at the top of my buttocks so it get aggravated when I sit, and since my work involves computers it's a little difficult to avoid.
Hope that helps.
