I live in a hostel. I am a very thin boy and also I am smaller than others. The older boys of our hostel use to disturb me and make fun of me. Today one of the boys slapped me on my head very strongly. There is no external injury but my head is spinning and I feel uncomfortable and dizzy. Will the dizziness and the uncomfortable feeling go away after sometime? Has the slapping on my head damages Brain? Is my brain okey?
