Can you define non length dependent for me? I'm not sure what mine would be considered. It started with mild tingling and mild numbness in part of my right foot and big toe area a couple of years back, but started to affect my left foot and legs about about 6 months ago, I now have weakness in both legs that bothers me more than the tingling and numbness. I do not have a whole lot of pain, occasionally I will get a burning sensation in my thighs but not everyday. I would say it's more of an uncomfortable feeling. I do know mine is large fiber, because it showed damage to the sheath and axons on my NCS, I'm not sure if I have small fiber involvement though.
