Digital artery conditions

Digital artery conditions are disorders in which the fingers or toes suddenly lose blood circulation, usually in response to cold. Also called Raynaud’s disease or Raynaud’s phenomenon, digital artery conditions can occur on their own, or may be associated with other conditions such as atherosclerosis, lupus, rheumatoid arthritis, scleroderma or repetitive injuries.

Risk factors

Digital artery conditions not associated with any other condition are more common in women, especially between ages 15 and 40. They also are more common in people who live in colder climates. Risk factors for secondary digital artery conditions (those associated with certain disorders) include conditions such as atherosclerosis, lupus, rheumatoid arthritis, scleroderma or repetitive injuries, and smoking.

Symptoms of digital artery conditions

Attacks can last from less than a minute to several hours. First, the affected area usually turns white. Then it turns blue and feels cold and numb. Lastly, the area turns red and begins to throb, tingle or swell.
