what youre experiencing is a concussion of which may range from mild, moderate or severe. what you describe sounds to me to be of the mild variety: slight dizziniess, inability to think clearly, ringing of the ears. this is common among boxers particulary those who often allow themselves to be hit. the only defense to this is - and sorry the redundancy- defense. you'll do well for yourself to stop eating punches as you cant box under the spell of the syptoms various levels of concussion impose on you. it hinders your ability to think on your feet
