Has your doctor ever discussed Fibromyalgia with you? I am not sure if the burning feet are related to Lupus, but I know for a fact that they are a symptom of Fibromyalgia. Many of us have Fibromyalgia as an overlapping condition with our Lupus. For me, the burning sensation is also in my arms and legs and can be unbearable at times. I've often had to sleep with ice packs on my extremeties in order to combat the burning sensation.
I am not sure if this is your issue, perhaps you can discuss it with your doctor. I wish you the ver best.
Peace and Blessings
Look For The Good and Praise It!
