What is Raynaud's disease? What are the symptoms?

First, some patients lack typical intermittent skin color changes, especially in the late stage, only pale or cyanosis.

Second: in severe cases, there are nutritional disorders on the finger tip skin, such as dry skin, muscle atrophy, brittle nail, and infection around the nail. When the finger artery is narrow or occluded, superficial ulcer and small area gangrene appear on the finger tip, accompanied by severe pain. After the ulcer is healed, spot like skin scar is left.

Third, the skin color changes are often regular, and the affected fingers are often symmetrical. The skin color changes are mostly developed in the order of the fourth, fifth, third and second fingers. The thumb is rarely affected because of more muscles and rich blood supply. The skin color changes begin from the distal segment and gradually develop upward, but rarely exceed the wrist, which all occur in the hands. Raynaud's disease of the toes is rare, and the skin of the ear, nose tip and lip is pale or cyanotic occasionally.

matters needing attention

Raynaud's disease can occlude small blood vessels, leading to finger tip necrosis. In severe cases, the pulp of the end of the finger may be flattened, gangrene, and the distal phalanx may be necrotic, absorbed, dissolved, shortened or amputated due to ischemia.
