Dysfunction in the sacroiliac joint, also called the SI joint, can sometimes cause lower back and/or leg pain.

Systemic lupus erythematosus is a much more serious condition than its cutaneous counterpart.

The symptoms of DLE can include one or more of the following: 1  Depigmentation (paleness) of the skin on the bridge of the nose. 2  Skin redness (erythema), especially on the bridge of the nose, face and lips.
