There is nothing magical in 'feel the pain' (also love,hate etc).
What about hunger and others? Your body and brain evolved to a current state which releases chemical substances to signal to other parts of body what's going on. Here cut arm is signaling with pain it's hurt and this will/may (after many layers of reduction) hamper your survival chances, thats why you have such signaling in place.
In essence, your pain feeling (and others 'high feelings like love/child etc') is no different than automatic closing your eyes because your eyelashes touched something or you moving out of warm environment because it's not comfort anymore to you or you drinking some water because you're thirsty (BTW try to trink about how that 'I'm thirsty' thought just appeared in your brain - who did it? ;) ).
The same as pain in principle, it's just a type of feeling. Physics can't not only explain them, it can't even define them, because they're subjective experiences.

I'm sorry, but this is completely irrelevant. When I discuss this people always describe what happens in the human body when we feel pain and how it's evolutionary advantageous - I don't get what's the point of that.
What's happenning in the body when we feel pain is not the question. The problem is why do we feel pain when those physical processes happen. Or more specifically, why do we feel pain when the physical particles in the brain are in certain configurations.
Isn't feeling pain the equivalent of negative reward?
Negative reward must be avoided, similarly, pain must be avoided.
Isn't this a good enough reason to feel pain?
