you sound like me some time ago last year before i had an operation on my nose. i cant remember the name of the operation but what they did was repair the tissues and things inside my nose (because i used to blow my nose very hard as a kid which fucked them up completely!) and straighten my nasal passages. after that i have had no problems and life is good! so if you recall yourself blowing your nose too hard or something talk to your doc about operations on repairing the tissues in your nose!
