Excision: Removal of the bone is an option, although not ideal. Casting the foot for 1-2 months and limiting your weight-bearing is another option. Some insurances may pay for use of a bone stimulator, but if not, some bone stim companies can get one to you through a financial assistance program as they tend to be very expensive.
