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?

No pain is not to tell you that you are harmed, pain is to keep you from using and protecting the part that is hurt. It is the body’s way to force you to stop using that body part, so it can get time to heal.
