Looks like my x-rays got munged up (they show red X’s) (will fix that tonight).
I twisted my ankle last July, and didn’t know my foot was broken until september. I did a half, an olympic, and a Full IM before I knew it was broken, and a sprint and Full after I knew 
I ended up having surgery on 12/14/09 to put a screw in - and was pretty useless from a exercise perspective until 3/17. I was able to start swimming around 3/5, bike on 3/17, and started running around april 1st (exact dates are in the thread.)
To answer some of your questions -
my foot hurt surprisingly little, but when it hurt it was a pretty sharp and at times crippling pain - but I was able to do almost all of my workouts with a constant stream of Ibueprofen. That said - I went around feeling something was wrong with my foot nearly 24/7.
As I said, I did a HIM on it less than 10 days afterwards - and my biggest concern coming in off the bike was that my heel (on the same foot) was still really sore from stepping on a rock during the run into the swim - so while it was sore - it was manageable.
Have you had x-rays yet? If you haven’t I would make sure you get them immediately. I would also recommend only doing the activity you and your doctor deem appropriate for your injury. After surgery my doc didn’t want me swimming or pool running because the ankle flexation would continue to pull on the fracture. So based on my experience you probably want to be pretty careful with moving things around and/or weight bearing.
I ignored advice to get x-rays until nearly 9 weeks post break - and ignored further advice by running on it for another 8 weeks, before finally doing the smart thing.
My advice - listen to your doctor - referencing rroof and perhaps another local doc and follow their advice. Don’t rush things from a fitness perspective - this fracture is a PITA so take it slow in coming back from this. I know it’s hard and you don’t want to lose fitness, but I put my body in a very difficult spot and gave it a very difficult task in fixing this thing - by being a bonehead.
Yes, I missed a lot of training time - but I have also just recently PR’d @ the HIM distance and am pretty much at life best fitness a mere 5 months after being allowed any sort of activity.
