Fibromyalgia Syndrome Fibromyalgia (fi-bro-my-AL-ja) syndrome (FMS) is a very common condition of widespread muscular pain and fatigue. Seven to ten million Americans suffer from FMS. It affects women much more than men in an approximate ratio of 20:1. It is seen in all age groups from young children through old age, although in most patients the problem begins during their 20s or 30s. Recent studies have shown that FMS occurs worldwide and has no specific ethnic predisposition. National Fibromyalgia Research Association by nfra.net |
