Well, if the manga doesn't touch on anything, then the next best piece of evidence is the anime. Kishimoto was supervising it, after all. I think its best to say that Pain canonically doesn't feel pain, as that is what was established clearly.

Bare in mind, there are obviously inconsistencies throughout the Naruto series. For example, when we first saw the Naraka Path's abilities, the only person who could see the King of Hell is the one who was about to get his tongue grabbed. Konohamaru couldn't see it when Ebisu was being interrogated. And Ebisu couldn't see it when Konohamaru's Clone was being interrogated. Ebisu got kicked right through it, in fact.

But then we have Itachi throwing Kunai at something that should only be seen by Naruto, and something that the Kunai should have just gone right through. Sorry for the spiel, but I think that 'Pain feeling no pain' proof is as good as its gonna get.
