My good friend had this problem. You could thump his nose and it would bleed. I cant remember what it was excatly but it had something to do with shallow capillaries...It took a very minor surgery he was back in action in a week or two
yea me to... its like cartorizing the nose. i did this several years ago, because nothing would make my nose bleed.
afterwards i dont really have much trouble with it. speak with your doctor.
