I have primary Raynauds and MS. I can't stand cold air on my fingers. I hate to take anything out of the freezer in causes pain just to hold it. I wear gloves when shopping. What I read there is a primary and secondary form. Secondary form to diseases like Lupus and scleroderma. I don't know if it has any connection to MS. I know that people with ME/CFS and Fibro have Raynauds. Mine seems to get worse each year.
