I have that problem, with the lupus attacking my nervous sytem. I have it in my hands, right arm and leg. I have to watch when I first stand up, because my leg may not want to move if it is numb. I figured that out about
3 years ago, I stood up from my pc and my leg wouldn't move. I was busy I had things to do so I keep trying to walk, I fell down instead. about
6 hours later I figured out that I had a problem with my foot. It turned out that I had broke my ankle in two places.
My Rhumy sent me to a nerve Dr. I had several test done and the neuropathy is spreading. There have been times that I couldn't move my fingers to pick up a pen. There are times that I will beat on my legs or hands to make sure they will work when I need them to.
