How do you explain the disorder of Fibromyalgia to others who question you as to what it is? I find that I start to explain that its a brain disorder that causes intermittent pain throughout the body which also leads to a sleep disturbances and extreme fatigue. I want to also explain that it causes disturbances to the autonomic nervous system that controls breathing, heart functions, and other organs like digestive etc. But, I never get to fully explain everything, as my brain fog interferes with my ability to explain it and the people usually cut me off mid-sentence as it's probably too much information for them to digest. What do you say when asked this question?
