A pain doctor I saw also stated that the trigger points for dx is not accurate. To the OP how is your D levels? I thought I was told that low D can also be a sign of fibromyalgia. Though my mom has low D and does not have fibromyalgia but does have osteoporsis. So even if you have low D does not mean you have fibro. Just a thought.
I often wonder since I developed other conditions too if one causes another or a person becomes more sensitive to conditions/problems. Who knows. When I have asked doctors some times they say it is a fluke.
