Fibromyalgia is no "immune disorder". If she had lab tests, they would all be negative. Although perfectly healthy, she managed to get a bogus diagnosis so that we taxpayers can pay for her upkeep.
Being idle contributes to her obvious mental disorder. If she was working she would have better things to do, people to be around, and a check on her break with reality.
Mayo Clinic
fibromyalgia isn't progressive, crippling or life-threatening. Treatments and self-care steps can improve symptoms and your general health.
Many of the symptoms of fibromyalgia mimic those of other diseases, such as low thyroid hormone production (hypothyroidism), polymyalgia rheumatica, neuropathies, lupus, multiple sclerosis and rheumatoid arthritis.
Diagnosing fibromyalgia is difficult because there isn't a single, specific diagnostic laboratory test. In fact, before receiving a diagnosis of fibromyalgia, you may go through several medical tests, such as blood tests and X-rays, only to have the results come back normal. Although these tests may rule out other conditions, such as rheumatoid arthritis, lupus and multiple sclerosis, they can't confirm fibromyalgia.
Fibromyalgia isn't progressive and generally doesn't lead to other conditions or diseases.
