I have raynaud's. How do I know if my feet are developing gangrene?
More profound colors
Raynaud's is usually a benign condition, unless you are a smoker. If you smoke, you may begin to develop restrictions of blood flow, which together with the spasm associated with raynaud's, might lead to tissue loss, though this is uncommon.
Profound color changes can occur but these usually normalize; if they don't, please see a vascular surgeon.
