So I am a very avid runner, marathons, halfs, 8ks and the such. Yet I have been having this problem of the late. I am training for the Chicago sprint triahtlon and have been developing an odd pain just between the bone and muscle area of my left shin on the inside of my leg. Its not all the time, but only when I run I can feel it. The first time I felt it was when I had an older bike that was too small for me and I thought it was from that, but since then I have upgraded my bike and shoes to fit me perfectly. The pain is still there. I have asked the people at my running store, but there is no answer from them. Its not shin splints, but a deeper pain. If anyone has had or might know what this is, anything would help!

I have attached a picture to kind of show where the pain is.
