Why do we get sore throats?

I know *how* we get sore throats (i.e. from viral or bacteria infections), which seems to be the only answers that come up when I try to ask this question online; what I'm curious about is the *why.*  We get a cough to try and loosen mucus, we get a fever to allow the body/immune system to work more efficiently, but why do we get a sore throat? What purpose does it serve physiologically, if any? Or, is it a side effect of something else?

It’s pain from inflammation. The pain itself doesn’t serve much physiological function beyond making sure you know something’s wrong with you, and thus hopefully avoid actions that would aggravate the inflammation site.

Inflammation is a common, physiological response to pretty much any damage to any part of your body (except a few special places where it is normally suppressed, such as your brain, or the inside of your eye globes), mainly mediated by your immune system, mainly for the purpose of facilitating further immune response and tissue repair. In the case of a sore throat, or in fact any infection, inflammation is induced by both the damage directly caused by pathogens, and by your immune response trying its best to fight off the pathogens.
