No, I haven't. The pain began over a year ago as a result of walking too much. It was before I was diagnosed with SFN. I went to ortho and xrays were fine. They put me in a boot and said it was a sprain. Same happened with my hand...a "weeding injury" and i wore a hand splint. Body was falling apart...was SFN. Will check.it out further though. Thinking maybe a cortisone injection may help. Thanks for response.
