You are right about the fact that one of the primary things that Lupus does is cause inflammation in various parts of our bodies and our internal organs. Lupus can cause inflammation in the sac surrounding the heart (pericaridtis), inflammation in the sac surrounding the lungs (pulmonary hypertension), inflammation in the joints (arthritis), etc. Also, Lupus makes us vulnerable to infections. Lupus can also cause problems with the kidneys which reveal themselves as protein leaks in the urine. Not everyone with Lupus will develop the skin lesions and there is a form of Lupus (Discoid Lupus) which primarily affects the skin. People with Lupus also suffer from "Lupus Headaches" and most of us suffer from some form of anemia.
Additionally, many of us with Lupus have also developed Fibromyalgia. Now, the symptoms of Fibromyalgia incude TMJ, IBS, sleep disturbances, headaches, fatigue, muscle aches.
In short, it is quite possible that you are suffering from some sort of auto-immune disorder and/or connective tissue disease. However, your doctors will have to run the appropriate tests and do lab work, take into consideration your symptoms and your history, follow the development of your symptoms and determine if you fit the criteria for Lupus or another auto-immune disorder. This process could take months to a year before you get a definite diagnosis.
