The damage is also there from sunburns. You can stop before it hurts, only to later find it reddenned the next day and such. Same thing with welding with insufficient protection - ie. no long sleeves. You can weld and find out a few hours later that you should’ve brought a long sleeve after all. Once it hurts when you are doing something, then it’s a really bad case.
But you feel the “reddening” as a heat on your body. Just put your hand on a sunburn, you’ll be able to tell you have burned long before you can even see it.
Even before it hurts, you can feel your skin getting itchy and dried out. But, if you’re indoors and not expecting to be burned, you might not notice, or might not realize what you’re feeling is from the disinfectant UV lights being misused as fun paint-glowy UV lights.
Maybe i’m just thinking of sun burns. You feel pain long before any actual damage occurs
If you start to feel pain it’s because your cells has been damaged and release immune stimulating substances which also irritate the nerves
