I was punch at the head but I dont feel any dizzy when I was hit just pain at the skull is it mean my brain didnt get any concussion except my skull?

Brain rattled! Any blow to the skull will "rattle the brain." If you have no symptoms, it obviously did not cause a noticeable injury. However, repetitive injuries, even with no symptoms at the time, cause more and more damage as time goes on and makes the brain more likely to be hurt with each episode. Peace, brother! Violence to you (by anyone) and by you (to anyone) is unhealthy to all (obviously).
