For most people, primary Raynaud’s is not serious and can be managed with lifestyle adjustments. However, secondary Raynaud’s can be more severe, as it may be linked to an underlying health condition. In some cases, poor circulation can lead to complications such as ulcers, infections, or, in extreme cases, tissue damage. If you experience severe symptoms, persistent pain, or skin sores that do not heal, it’s important to seek medical advice.
