A callous-like sore on the pinky toe that seems to be affecting a nerve is definitely worth paying attention to, especially with lupus in the picture. There are a few lupus-related things that could be contributing to this.
Here are some possibilities to consider:
- Chilblain lupus — a rare form of lupus that affects the skin, causing painful sores or plaques on the toes, fingers, soles, and heels. These can appear red, purple, or darker depending on your skin tone.
- Raynaud's phenomenon — a lupus comorbidity that affects blood flow to the fingers and toes, which can sometimes lead to ulcers or sores on the toes.
- Peripheral neuropathy — lupus-related nerve damage that can cause numbness, tingling, or burning sensations, which might explain the nerve involvement you're noticing.
The most important step is to bring this to your doctor or rheumatologist as soon as possible, especially since it seems to be progressing toward a nerve. They may refer you to a podiatrist (foot specialist) who can work alongside your lupus care team.
In the meantime, keeping your feet warm and protected can help, particularly if Raynaud's or chilblain lupus is involved.
