Hi Tiffany -
I've had a lupus dx for about 7 years, have a couple of books about it, and have never heard of lupus making veins smaller. Interesting, but what a bummer! I know if someone has had a lot of IVs (like for dialysis, chemotherapy, or frequent illnesses), then their veins get harder to find and stick.
Sorry about those kidney stones. Hope they'll somehow disappear without bothering you.
Wishing you well! Barbara
