Living with Raynaud's Disease

Raynaud’s disease is a condition that causes some areas of the body to feel numb and cold as a result of cold temperatures or stress. Areas of the body that might be affected are the fingers and toes. In Raynaud’s disease, the small arteries that supply blood to the skin become narrower. This limits the flow of blood to affected areas. Raynaud’s disease may be caused by smoking, carpal tunnel syndrome, or injuries to the hands or feet. Symptoms of Raynaud’s disease may include cold fingers or cold toes.

Medications that help widen arteries and increase blood flow may be used to treat Raynaud’s disease. Calcium channel blockers such as amlodipine (Norvasc) work to relax and open small arteries in the hands and feet. Side effects may include lightheadedness. Alpha blockers such as prazosin (Minipress) and vasodilators such as nitroglycerin cream also work to relax arteries. Side effects may include dizziness.
