I got this information from WebMD. Here are the symptoms
If you have lupus (systemic lupus erythematosus, or SLE), you may be extremely tired, have skin rashes, or have joint pain. If the disease is more serious, you may have problems with your kidneys, heart, lungs, blood, or nervous system.
Lupus symptoms depend on what body organs are affected and how seriously they are affected.
Fatigue: Nearly all people with lupus have mild to extreme fatigue.
