I know how you feel, I broke my big toe by being clumsy and stubbing it on the end of a couch! lol The worst part about it was I went to the doc to see if he could do anything about it and he said they should do an x-ray to see if it was broken, it was, then he said they couldn't do anything for me! If I knew that I wouldn't have paid $70 for a stupid x-ray!
Anyways, try riding a stationary bike, and make sure you are closely monoriting your food since you won't be exercising as much.
