How do I convince my orthopedic to cast my foot?

The only thing that casting will help is if he needs to reset and keep your foot in place. Casting won't stop the pain, only RICE will. Try resting and your doctor can determine if you need a cast. Plus, casts suck. It's the middle of summer.... Trust me, you don't want sweaty stinky cast for the next eight weeks. I have experience in that area!!!
