Skin color changes on the feet with lupus are definitely something worth paying attention to. Lupus can affect the skin in several ways that may explain darkening or discoloration in that area.
One common cause is livedo reticularis — a lacy or net-like pattern under the skin that can appear pink, red, purple, or brown. It tends to show up on the legs and feet, and can worsen in cold temperatures.
Other possible lupus-related skin changes on the feet and lower body include:
- Purpura or petechiae — small or larger discolored spots caused by tiny blood vessels leaking under the skin, appearing deep purple or brown on darker skin tones
- Erythema nodosum — painful, discolored bumps that often appear on the shins, ranging from red to purple or brown
- Raynaud's phenomenon — a lupus-related comorbidity that affects blood circulation in the fingers and toes, which can cause color changes
Dry skin can also be a lupus symptom or a side effect of certain lupus medications like corticosteroids. It's always a good idea to flag new or worsening skin changes with a rheumatologist or dermatologist, especially if the dryness or discoloration is spreading or uncomfortable. They can help pinpoint the cause and suggest the best treatment approach.
