Have read lots of info and think I have shin splints in left leg. Had pain for over a week which is bearable once I get going but am worried I might be causing damage. Really don't want to stop now as on week 7 r2. Been advised to run on grass. Will it be more difficult running on grass? And could it just be my body just getting used to the longer runs? I've had other aches and pains but they've gone away and the aches have moved to different areas but this one's staying. It hurts a bit just walking. And it's weird it's just the one leg!
