It sounds so much like lupus. But, since we are not doctor's here, we cannot tell you if it is or if it is not. If your doctors find that it is not Lupus, it still sounds as if it could be one of the other autoimmune diseases. The treatments for the symptoms you described would essentially be the same if it were another autoimmune disease. The goals of treatment for autoimmune disorders are to reduce symptoms and control the autoimmune process while maintaining the ability to fight disease. The symptoms are treated according to the type and severity.
Autoimmune disorders are conditions caused by an immune response against the body's own tissues. Immune system disorders occur when the immune response is inappropriate, excessive, or lacking. Autoimmune disorders develop when the immune system destroys normal body tissues. Normally, the immune system is capable of differentiating "self" from "non-self" tissue. Some immune system cells (lymphocytes) become sensitized against "self" tissue cells, but these faulty lymphocytes are usually controlled (suppressed) by other lymphocytes. Autoimmune disorders occur when the normal control process is disrupted. They may also occur if normal body tissue is altered so that it is no longer recognized as "self." The mechanisms that cause disrupted control or tissue changes are not known. One theory holds that various microorganisms and drugs may trigger some of these changes, particularly in people with a genetic predisposition to an autoimmune disorder.
Autoimmune disorders result in destruction of one or more types of body tissues, abnormal growth of an organ, or changes in organ function. The disorder may affect only one organ or tissue type or may affect multiple organs and tissues. Organs and tissues commonly affected by autoimmune disorders include blood components such as red blood cells, blood vessels, connective tissues, endocrine glands such as the thyroid or pancreas, muscles, joints, and skin.
Symptoms of autoimmune disease vary widely depending on the type of disease. A group of very nonspecific symptoms often accompany autoimmune diseases especially of the collagen vascular type and include:
fatigue, dizziness, malaise (nonspecific feeling of not being well), fever, low-grade temperature elevations.
Specific autoimmune disease results in: destruction of an organ or tissue resulting in decreased functioning of an organ or tissue (for example, the islet cells of the pancreas are destroyed in diabetes )
increase in size of an organ or tissue (for example, thyroid enlargement in Grave's Disease).
Here is a list of autoimmune disorders:
type I diabetes
systemic lupus erythematosus
