What is calcification of veins? Any remedies? Does this mean that all of the veins calcify?

My mom was told the swolen areas on either side of her neck/shoulders are caused by calcification of her veins. Is that like hardening of the arteries? She has Lupus and is diabetic. Is there anything she can do to reverse of help it? I guess the doctor also told her to take some medication for her cholesterol which is a bit high but not a lot. Does her cholesterol level have anything to do with the calcification in her veins? Confusing. Thanx.
