Lupus is hard to explain. The best way I tell people is that I am allergic to myself. There are cells in your body that attack bad cells and make them go away.

The cells in my body think **everything** is bad and so attack everything.

That's it in a nutshell, I am sure other people have better definitions.

Go on www.Lupus.Org or www.Arthritis.Org and get a better look. Or ask a rheumatologist, or ask your doctor (if he/she is savvy in lupus).
