What causes Raynauds?
Although we know many of the common triggers that create Raynaud’s episodes in individuals, the basic cause of Raynaud’s in most cases is still a mystery. However, there has been a link established between Raynaud’s and some autoimmune diseases (although it must be emphasized that the vast majority of Raynaud’s patients do not have those diseases). Raynaud’s may precede such diseases by years. Raynaud’s also may signal damage to the blood vessels caused by occupational injuries (from using jackhammers, for example), trauma, excessive smoking, circulatory problems, drug use or exposure to certain chemicals and toxic substances.
