Because you don't just hurt, you suffer. Across the spiritual spectrum people report that "enlightenment" brings a radical reduction or elimination of self-inflicted suffering, and a profound inner peace. This jives with my limited experience of it as well.

Someone kicks you in the shin, it causes pain. If it triggers a whole internal loop of fear and worry and anger and revenge and trauma and suffering, then you've hit upon your ego which you're unable to let go of. If your internal experience isn't sticky, then before you know it, the pain has dissipated and you're on to whatever the next present moment brings.

That internal loop is what there is to "fix".
