Why go to a grip that causes pain (and perhaps reinjury or at least irritation)?
So a couple months ago I injured my shoulder and started doing closegrip bench instead of regular grip bench. Now I decided to go back. I've been making the grip just a little bit wider every session and now I reached a point where I get weaker if the grip gets wider. So my closegrip bench is stronger than my regular bench. For optimal strength development do I keep benching with a close grip because I can move more weight that way and thus gain more strength? Also my shoulder still hurts. So when and how do I go back to regular benching?

You need to define how close is 'close' and how wide is 'regular'.
Don't get disappointed, Konstantin Konstantinovs benches close grip.
