All the social construct and higher-level understanding aside, what is pain in terms of chemical and physical interactions with the neurons? For example, dopamine (and others) cause happiness…anything similar to that with pain?

Oooo… fun question!
Nerves take signals and move them to the brain for us to process. From the vibration of your phone, to feeling the table, to groping your loved one, all go through nerves.
The difference is the location. Nerves to through ‘tracts’ that go to certain parts of your brain. Pain and temperature tend to go through the tract to your thalamus, which handles emotions.
However, that’s not the only signal! The same signal will also make a stop in the spine, and activate motor nerves, causing movement. That’s why when you touch something that’s painful and you don’t expect it, you pull your hand back. That’s called a reflex.
