"shin bite"

i searched around and i couldnt find anything on this specific problem.  last year my shins always hurt and they still hurt this year.  it doesn't feel like shin bang cause my boots are tight and my shins aren't moving around and hitting the cuff.  my hair gets ripped out into my socks.  its a weird feeling but when i flex my boots its really uncomfortable and like a bunch of little pins sticking me and rubbing.  just general discomfort and after a while it really starts to hurt and i can't pressure my boots forward.  obviously i need to be able to flex my boots hard to ski well. so i was reading up online trying to figure out why my shins hurt so much and i came across the term "shin bite."  it comes from the boots tongue not distributing all the pressure correctly.  thats why the pain is real intense in certain spots and spreads around a little.  supposedly i'm supposed to change my boots tongue so it distributes all the pressure better all over my shins, not just at the top and in certain spots.  my question is how do i do this? do i need new boots?  have any of you guys had this before and what did you do? what worked and what didn't?  oh yeah and i was reading that shaving your shins helps, and since my hair was getting ripped out i went ahead and shaved my shins.  im stilling getting the same discomfort and prickly, sharp pain.  i just want to be able to flex my boots forward with comfort and apply as much pressure as i can without pain.
