In many cases, the condition begins with feelings of numbness. The affected area often turns white (called pallor) because of decreased blood flow and then may turn blue because the area is not getting enough oxygen. Swelling also may occur and the patient may lose feeling in the affected area. When the area is warmed or stress is relieved, blood flow resumes causing the area to turn red. At this point, symptoms may include throbbing or prickling pain.
