Good news - The x-rays came back and my foot is not fractured.
Bad news - My foot is still stiff, no less swollen and I still can't walk on it without pain.
The good 'ole doc says to "take it easy." Remember running break I took last week? Sure, it helped. By the weekend, my foot wasn't bothering me a bit. And I gave it one more day of "easy" on top of feeling pretty darn good. So yea, clearly I need to take it easy for longer than a week. That's a lot easier said than done. And while I'm taking it easy I'm also not training. Which will make that half-marathon pretty difficult.
