Re: does nikyo hurt?
The best nikyos I've felt induced collapse. There was no pain, just a switch flicking from off to on, and I went from stood up to not. Nikyo seems to present the body with a moment of peak pressure that convinces your body to try and get lower/underneath it. Pain isn't part of the equation, unless the duration increases and the pressure decreases. I suppose this could be done accidentally or intentionally. A lot of beginners have nikyos that cause a fair amount of pain, but don't take your balance.
