here's my story:
got started up about six months ago, got to about 15-16 mpw, feeling really good. was running about 7:30-8:00 minute miles and really proud.

6 weeks ago i got started marathon training for december.i got moving, had changed my stride to my forefoot and when i got to my 6-7 mile days i got a lot of pain in my hips and shins. after 2 weeks recovering from shin splints i moved my stride back to my heel (more of a midfoot landing, really) and all seemed to be good.

now, just last weekend i ran 6 miles, day off, then 3 miles and the shin pain returned. i decided not to push it and haven't run in a week, but i have a pain in my shin still.

difference this time is that while the shin splint pain was at the top and bottom of the shin, this is n the middle. the shin split pain pretty much only hurt when i moved my legs, this pain can be at any time, even lying down. the splint pain was consistent while the leg bore weight, the new pain comes and goes, at times throbbing.

the pain is still medial, not right in the front on the bone, so i've some hope, but does this sound familiar to anyone? more to the point, does it sound like a stress fracture? i'm lgoing to see the doc on it this week, but i wanted to get some input before i look like an alarmist dork.
