I am a male and have just asked the same question on another forum. My understanding is that fibro is thought to be highly under diagnosed in men. If I remember right they say that men are about 2% of those diagnosed with it. Like some of the other that posted, I have anxiety, sleeplessness and pain that has progressively and slowly gotten worse over the last few years before finally getting the diagnosis.
I take medication for the anxiety and to help me sleep. I haven't been given anything that really has hit the pain/aches... Haven't tried lyrica or cymbalta or any of the other medications mentioned here. I think it will be a trial and error phase for me for a while since I was just given the official diagnosis last month. My GP has taken a lot of time and continues to research the treatment regimes being used and I think it will begin to take some of the frustration I have had in the past away. It was kind of a relief to finally have a name attached to my condition, but at the same time disappointing that there is little known about it and the pathways to what will control it are so varied. Its not like a broken bone, where they set it, cast it and it goes away over time.
