Fibromyalgia

I was diagnosed with fibromyalgia about 9 years ago, after a long time of leg pain, whole body pain and exhaustion.  I have read that fibro is often experienced by those on the spectrum as it is a heightened sensitivity to pain. Has anyone else here experienced the symptoms or been diagnosed? I think I manage my fibro symptoms quite well, but some days I feel like I have been hit by a truck. How much of this is also as a result of burnout, I'm not sure.
