Deidara has the highest pain tolerance

Care to elaborate? and by "care", I mean "bitch get to explaining."

Because being in pain doesn't hurt as much if you recover rather than someone who can't heal and has to deal with the after effects of it over a period of time.

Not if it happens that quickly. Not to mention how adrenaline works. If you're suddenly stabbed, you don't feel the pain. At least I didn't at first.

If it's something like what happened to Obito or Kushina and Minato it would be impressive.

I'm certain internal damage would impede consistent blood flow, but I'm not a biologist, so I wouldn't know this.

Tsunade still survived after being mutilated by Madara and significantly low on chakra when even the likes of Gaara was unconscious. That still counts for something.
