Asking this as I have a horrible throat infection making it incredibly painful to swallow, and therefore difficult to eat and drink. I have to stay on top of my painkillers every four hours or the pain starts to come back, I’d just love to know how this actually works.

Pain is just a feeling – so if you don’t feel it, it’s not there. When your body gets damaged in some way, it sends signals to your brain to let you know you’re hurt. Painkillers interrupt the pain signals before they get to the brain. The actual damage is still there – in your case swollen and inflamed tissue from infection – but the pain is gone.
