Lupus Warning Signs: How to Recognize and Manage This Elusive Autoimmune Disease

13. Raynaud's Phenomenon

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.

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