I went to the docs because I have been feeling very low energy lately one of my chief complaints was that laterly my hands would turn ice cold, very frequently. Stress makes it worse. My doc felt my hand ( I was having a flare up at the time) and new right away what it was. We are now doing blood test to see if there is an underlyig issue which I do suspect is there.
Stay warm, gloves and fingerless gloves and socks are wonderful things, even in summer. Do you have any other symptoms? Some of us here are in the process of being diagnosed with other connective tissue disease, some of have primary Raynaud's and some of us have secondary Raynaud's to lupus, scleroderma, and such. I hope you are having a good day and staying warm.
