Shin splints..?

I think I might have my first shin splint! I hope not, because I have a race on the 19th! My 1st ever!! I was running in NC (visiting my sister for a week and a half) and ran by the Harris Teeter and past Wendy's but when I got on the trail on my way back I think I hit a bad rock or something a weird way. I have a bit of pain.. I'm going to ice it tonight and maybe go for a walk tomorrow instead of running.. I sure hope it's not my first injury. I will be totally depressed.. =(

I also ran without my iPod today. Was a good experience. I am going to do this once a week. :) Be totally tech free!!
