But this year, researchers finally began to get a handle on the condition.
"What's happened is in 2013 there's been this absolute explosion of papers," says neurologist Anne Louise Oaklander at Massachusetts General Hospital in Boston. "The whole view on this has shifted."
Oaklander published two studies this year showing that half or more of the cases of fibromyalgia are really a little-known condition affecting the nerves. People with this small-fiber neuropathy get faulty signals from tiny nerves all over the body, including internal organs, causing an odd constellation of symptoms from pain to sleep and digestive problems that overlap with symptoms of fibromyalgia.
Neuroscientist Frank Rice and a team based at Albany Medical College also discovered that there are excessive nerve fibers lining the blood vessels of the skin of fibromyalgia patients - removing any doubt that the condition is physically real.
These fibers in the skin can sense blood flow and control the dilation...
