hi there
I have had both vascular problems (reynauds and a blocked artery in my shoulder) and neuropathic problems with my hands.

As far as I am aware, vascular problems are accompanied by a drop in temperature and changes on colour in the affected extremity. I have never heard of vascular problems that cause neither. The first thing that both my rheumie and vascular surgeon check with my hands is colour and temperature when looking at my vascular problems. It makes sense, because if not enough blood is reaching an extremity then it starts going cold. When my hands are numb from reynauds, they are a waxy, bloodless white colour (usually just my fingers).

I also have numbness in my feet (permanent) from neuropathy. This is not associated with any change in temperature or colour, I just can't feel them. They can still be affected by reynauds though, as that is an entirely separate phemonina. I have both reynauds and PN as part of my lupus.
