For example, I cut my arm and I immediately feel pain. Pain is there to notify me that something is wrong or that I’m injured, but now that I’m aware and that I’ve taken care of it (say poured some disinfecant and wrapped it up) why do I still feel that pain. Why can’t our brain know that the wound is not dangerous anymore?

Because our nerves that first detected the injury, still feel the wound is not healed, so they continue to send the message up the spinal cord.
