I guess mine is non length dependent since my upper thigh showed more significant damage then my foot at the time of the test. I bet if they tested it now, the foot has caught up.

Anyway, are there different causes for the two types? Mine started in my left leg and hand. It was nothing but an annoyance for about a year then it went to my neck, face, shoulders, and right limbs as well. It is in my whole body now except for my abdomen.

Are there different protocols and research for the etiology of NLD vs LD?
