Often Raynaud's has no known cause. (This is sometimes called primary Raynaud's.). Raynaud's is usually a symptom of another disease, such as lupus, scleroderma, rheumatoid arthritis, or atherosclerosis.It may also be caused by taking certain medicines, using vibrating power tools for several years, smoking, or having frostbite.uring an attack of Raynaud's, the body limits blood flow to the hands and feet. This makes them feel cold and numb and then turn white or blue. As blood flow returns and the fingers or toes warm up, they may turn red and begin to throb and hurt. In rare cases, Raynaud's affects the nose or ears.
In people with Raynaud's, the sensitive blood vessels overreact to cold temperatures and become narrower than usual, significantly restricting the blood flow. Symptoms can be triggered by mildly cool weather, getting something out of the freezer, or running your hands under a cold tap.
