I have rsd of the right foot, and have lots of lsb's. The last set (1 week apart gave me tremedous relief) So they can work. I was injured at work also it will be 3 years in May with a crush injury to my right ankle and splinter the Tibia. I have 2 surgeries. One with hardware one to remove almost all of the hardware.

For the dr. to tell you they don't work is incorrect. This is usually the first step in treatment. I highly recommend trying it before having an implant.
