Your girlfriend will probably need to see a rhumatologist. He may prescribe anti-depressants, enough rest, moderate exercise and good nutrition. I know this because my 13 year old daughter has fibromyalgia. When I inquired about a "cure", I was told that this is a chronic condition that she would be managing all of her life. But there is hope. With proper treatment, your girlfriend should be able to lead a normal life. My daughter does. Good Luck!
