I can't begin to tell you how many people I have recently come across that are completely misinformed about Fibromyalgia. There are some that just think it's arthritis and there are others that still want to believe that it's a syndrome and not a disease. I'm not sure why people want to hold true to that syndrome thing. Many sites stopped calling it FMS for short several years ago. It's now called FM because it is a disease-- period.
But, for those of you that still need proof that it's an honest to goodness disease, here's some proof from a very reputable website called WebMD-- you may have heard of it. Also, please note that this article is four years old which means that all of us who have this DISEASE have known it for years.
