Lupus Warning Signs: How to Recognize This Elusive Autoimmune Disease

Cold Fingers and Toes

Raynaud’s phenomenon, common in lupus, causes fingers and toes to turn white or blue in response to cold or stress. Poor circulation can lead to numbness, tingling, or pain, making everyday tasks difficult. In severe cases, ulcers may form on the fingertips.

If your fingers or toes frequently change color in cold weather or stressful situations, it may be a sign of lupus-related circulation issues.
