Yes, try looking up peripheral neuropathy. It seems to be common in some AI diseases, especially in Sjogren's. I think that it is common in Lupus, too. Hopefully, SaySusie or Rob will comment on that.
PN often starts in the toes and feet, and then gradually works its way to the knees, and then jumps to the fingers and hands. I have it in my feet, so my toes are cold and numb, and I feel like I'm wearing socks even when I'm not. It's been affecting my fingers and hands a bit lately.
Hope this helps.
