Complications
By Mayo Clinic staffIf Raynaud's is severe — which is rare — blood circulation to your fingers or toes could permanently diminish, causing deformities of your fingers or toes.
If an artery to an affected area becomes blocked completely, sores (skin ulcers) or dead tissue (gangrene) may develop. Ulcers and gangrene can be difficult to treat.
