I found this on the Mayo Clinic website of all places! If this condition is not crippling or progressive, why have I gotten worse over 12 or so years, and why do I have trouble walking?? READ BELOW Fibromyalgia By Mayo Clinic staff Overview Article sections: Overview Signs and symptoms Causes Risk factors When to seek medical advice Screening and diagnosis Complications Treatment Self-care Coping skills Complementary and alternative medicine You hurt all over, and you frequently feel exhausted. Even after numerous tests, your doctor can't seem to find anything specifically wrong with you. If this sounds familiar, you may have fibromyalgia, a condition that affects an estimated 3 million to 6 million people in the United States. Approximately 80 percent to 90 percent of affected people are women. Fibromyalgia is a chronic condition characterized by fatigue, widespread pain in your muscles, ligaments and tendons, and multiple tender points — places on your body where slight pressure causes pain. Previously, the condition was known by other names such as fibrositis, chronic muscle pain syndrome, psychogenic rheumatism and tension myalgias. Although the intensity of your symptoms may vary, they'll probably never disappear completely. It may be reassuring to know, however, that fibromyalgia isn't progressive, crippling or life-threatening. Treatments and self-care steps can improve symptoms and your general health.
