What are the signs and symptoms of lupus?

Lupus may be hard to diagnose. It’s often mistaken for other diseases. The signs of lupus differ from person to person. Some people have just a few signs; others have more.
Common signs of lupus are:

  • Extreme fatigue (feeling tired all the time)
  • Painful or swollen joints
  • Muscle pain or weakness
  • Unexplained fever
  • Chest pain with deep breathing
  • Depression, trouble thinking, and/or memory problems
  • Unusual hair loss (mainly on the scalp)
  • Pale or purple fingers or toes from cold or stress
  • Red rash or color change on the face, often in the shape of a butterfly across the nose and cheeks
  • Sensitivity to the sun
  • Low blood count
  • Swollen glands

Other signs are mouth sores, unexplained seizures (convulsions), “seeing things” (hallucinations), repeated miscarriages, and unexplained kidney problems.
