Ouch! Be careful with it. Robbie can tell you all about what you should and shouldn't do on that front...
Let me know if you want any advice on alternative training - we'll need to figure out what works for you but I have a few suggestions.
Get an X-ray or a bone scan asap to find out if its actually a stress fracture. Until then I suggest you don't do any high impact activities, or any activities at all if it's painful. Do some brain training instead.
Good luck with it! Follow Rhombus' advice.
I don't think its too bad, because when I step on it it doesn't hurt even though I feel it. So I'm trying not to weigh it and resting it until it goes away. The doctor said that it probably won't show up on an X-ray or MRI, but I am going to a foot specialist soon, and I'll see what they say.
Otherwise I'm just going to do core until I can jog on it. And then start jogging with softer shoes.
See my email Michael. This isn't the kind of thing to be treated by anecdote. Calgary is one of the leading sports medicine cities in the world and you need to get this sorted out properly.
