The Categorization of Pain in Systemic Lupus Erythematosus.

Systemic lupus erythematous is a systemic autoimmune disease that can cause severe pain and impair quality of life. Pain in lupus can arise from a variety of mechanisms and is usually assessed in terms of activity and damage. In contrast, categorization of symptoms as type 1 and type 2 manifestations encompasses a broader array of symptoms, including widespread pain, fatigue, and depression that may track together. The categorization of symptoms as type 1 and type 2 manifestations can facilitate communication between patient and provider as well as provide a framework to address more fully the complex symptoms experienced by patients.
