ELI5: Why does a burn still feel hot even after running it under cold water?
gpt
The damaged area is more sensitive, meaning nerves are firing off more signals with less stimulus required, and the area is inflamed meaning the body saturated the area with blood to jumpstart the healing process.

Lots of warm blood+ extra heat sensitive nerves = constant signals that the area is hot.
