The difference between Raynaud’s disease and Raynaud’s phenomenon, Raynaud’s disease is relatively more serious, Raynaud’s phenomenon is just a phenomenon. First of all, Raynaud’s disease, its typical onset of cold stimulation or emotional excitement will appear pale skin, dry, numbness and cold and tingling sensation at the end of the fingers, can be frequent attacks throughout the year. Raynaud’s phenomenon is different, the attack is relatively mild. Another is like this Raynaud’s disease, more than the plant nerve dysfunction, such as easily excited, easily impulsive, suspicious, depressed and other such conditions, Raynaud’s phenomenon is generally not, some times also accompanied by the manifestation of the original disease. Raynaud’s disease can cause occlusion of small blood vessels, resulting in necrosis of the ischemic end of the finger, and in severe cases, flattening and gangrene of the terminal phalanx can occur. The end phalanges can become necrotic due to ischemia and be dissolved by resorption, which can lead to shortening of the finger and even amputation. In some patients with low resistance, ulcers occur due to ischemia of the extremities, which may lead to osteomyelitis and sepsis. So Raynaud’s disease is quite serious, but the mere Raynaud’s phenomenon does not necessarily mean that there is this disease.
