I don't know about Dr. Potter, but I have heard that Dr. Filler's neurography will almost always show scar tissue, at least to him, if not to someone else looking at the same images. Then too, there was always the issue of whether a surgical procedure to resolve an entrapment would just create it's own scar tissue. That said, there were RSD patients in town who swore by him a few years ago - roughly 8-10 years back - but I frankly haven't heard his name raised in the local CRPS community in a long time.

While the water massage technique sounds intriguing, I could easily imagine that it might be difficult to balance the amount of force necessary to dislodge to old scar tissue with that which could sever the nerve entirely. In any event, I wouldn't be comfortable doing it without first seeing published human studies in a peer reviewed journal, and involving the sciatic nerve at that.

Of course, imposing a published peer reviewed study requirement could inject conservative bias, where new ideas are sometimes difficult to publish in established [read: Establishment] medical journals. On the other hand, with the proliferation of peer reviewed online journals, it's probably easier for a good study to find its way to publication than it once was.

For what it's worth.
