Chris @artscaping I need to clarify something. I think the reason the soncicare is so effective for Linda is that she only has PN in her feet & ankles. I don't think the sonicare would work as well in parts of the body where there is more fat tissue. Feet are mostly skin over bone on the tops and some pretty firm and tough skin on the bottoms. If one were to use it in certain other areas, like the stomach or the thigh, for example, it might not work so well. Just my theory. I don't know for sure as Linda only does it on her feet/ankles. Another thing is, even though the itch feels deep in her feet, deep is a relative term. I mean the deepest part of a foot is only a few centimeters in whereas a deep itch in the torso can be inches deep. I know this is pointing out the obvious but just to complete the explanation of why the sonicare works on feet but maybe not as well elsewhere.

She had this the worst during the April-June 2019 timeframe. That was when it was the most severe, and for her scary as it was SO intense. It seemed to become less regular and more sporadic after that (helped by the sonicare), with bouts occurring and then stopping. But she got into the habit early on of NEVER giving in to the scratching impulse so that probably helped too. At this point I think it has become a less prominent component in her overall constellation of problems.

Best, Hank
