ELI5 : Why does rubbing your head when you hit it make it feel better?

Nerves feel stretch (baro) temperature, pain, pressure. You can only feel one at a time. Pressure beats all in this game of rock, paper, scissors. When you cut yourself and squeeze the cut finger hard you feel the pressure but not the cut. Rubbing hard is a form of pressure, beating out pain.
