This article explains how fibromyalgia with painful lumps located under the skin called lipomas could actually be Dercum's Disease. Written by Dr. Nathan Wei for the Arthritis Treatment and Relief website.
It's estimated that fibromyalgia affects approximately 10 million people in the United States. Fibromyalgia is classically characterized by chronic pain, particularly muscle pain, fatigue, sleep disturbances, brain fog or cognitive impairment, depression and painful tender points throughout the body.
The pain of fibromyalgia can be intense. Because there is no lab test or X-ray to confirm a diagnosis of fibromyalgia, some patients were once led to believe this pain was "all in their heads." But the medical community now accepts that the pain of fibromyalgia is real. Research suggests it's caused by a glitch in the way the body perceives pain.
