I broke my leg about a week and a hakf ago and my foot is stinging off and on.?

You could have a trapped nerve in the leg, this would cause numbness and also shooting pains, it could also be caused by swelling. I would seek medical advice if possible because if it is a trapped nerve you may do damage to it. Sorry to hear about the break, you did a good job to break both, hope it works out, good luck.
