I always reccomend talking to your coach and/or a doctor, with that said: If the pain feels like it is straight down the center of the shinbone then that sounds like the normal too much too fast shinsplint, but four weeks sounds like a long time. If the pain feels like it is slightly on the side of the shinbone then that sounds like an over pronation issue. To correct too much too fast shinsplint you need to strengthen the muscle, if you have a one lip on front your couch tuck your toes under it and lift them up with the heel remaining on the floor, and put pressure on it (don't flip the couch). Do a few repetitions. In lieu of a couch you could fill a purse or soft bag with a soft weight (sand like) and put that on top of your toes. If it is an overpronation issue go to a technical running store. I hope that helps a little. And I reiterate, I am not a doctor, and did not play one on TV (although I did play Caesar once on stage) or stay at a Holiday Inn Express. Also talk to your coach. Good Luck Rick
