How does systemic lupus affect the feet?

Lupus can be associated with damage to the connective tissue in the feet, which means that the feet have less padding and walking (especially over rough surfaces) can make them sore. Sometimes lupus is associated with calcinosis, the formation of hard lumps of calcium in the skin, and these can affect the feet, causing painful ulceration. Despite this, many lupus patients never have any problems with their feet.
