Here's my upside-down way of handling pain.
I don't try to ignore it. I focus on it.
You see, I'm a curious person and my curiosity is a big driver for me. So ignoring it doesn't work for me. I ask myself questions, I focus on it. Where's the pain, what sort of pain, does it vary...
After all, it's intrusive anyway, so I try to change my relationship with it.
The thing that then helps is my scatterbrain and distractibility. My mind drifts to other topics, and having told my subconscious that I know why this 'alarm' is going off, it jars less. Yes, it's still bad, but it doesn't have the same feel.
It's like a fire alarm. It goes off. Panic stations. Look at clock - ah, weekly fire drill. If you feel ok, you barely notice it; if you don't, it bugs you. If you can't reassure yourself it's a drill, the panic continues.
Ok, so you've got pain. Your brain is saying "Help, emergency, danger!" So you tell it that no, it's ok, it's supposed to hurt because that's to tell you to take care of it. No, it probably won't make the pain go away, but it might take the edge off the distress.
The other thing is that whilst you're probably not supposed to touch the site of the wound, maybe see if there are any tender pressure points in nearby muscles that you can press to ease them a little. Even if you can't, it'll focus your mind on something different.
But that's just what works for me, not necessarily for you.
Still, if worst comes to worst, you'll simply not sleep for several weeks, which will drive you mad, which won't be a problem because you're mad already...oops, well, what I meant was...er...I think I'd better go and leave you in peace.
Or maybe not peace, maybe drown out some of the pain with loud music.
